5. Modbus RTU, CIM 200 setup

Fig. 2 CIM 200 Modbus module

Use a screened, twisted-pair cable. Connect the cable screen to protective earth at both ends.

Recommended connection

5.1 Setting the Modbus transmission speed

Set the transmission speed correctly before the CIM 200 Modbus module is ready to communicate with the Modbus network. Use DIP switches SW4 and SW5 to set the transmission speed. See fig. 3.

Fig. 3 Modbus transmission speed

DIP switch settings

Available transmission speeds in bits/s: 1200, 2400, 4800, 9600, 19200 and 38400.

The first three transmission speeds are only available via software settings, whereas the last three are available via DIP switches.

Default transmission speed is 19200 bits per second, as per the Modbus RTU standard.

Software-defined

When SW4 and SW5 are set to "software-defined", writing a value to the holding register at address 00004 will set a new transmission speed.

Use the following values for software-defined transmission speeds:

This value is set to 1200 bits/s as default.

The communication interface does not support transmission speeds above 38400 bits/s.

The software-defined transmission speed value is stored in the communication interface and remains after a power-off.

5.2 Setting the parity

You can set the parity either manually by using SW3 or via software-defined settings.

Manual setting of parity

Default byte format (11 bits):

• 1 start bit

• 8 data bits (least significant bit sent first)

• 1 parity bit (even parity)

• 1 stop bit.

The default setting of the CIM 200 Modbus module is even parity (1 stop bit). It is possible to change the parity using DIP switch SW3. You can change the parity no parity (2 stop bits). See fig. 4.

DIP switch settings

Software-defined parity and stop bits

When SW4 and SW5 are set to "software-defined", the value in the holding registers at addresses 00009 and 00010 will override the setting of SW3. See figs 3 and 4.

The software-defined parity and stop bit values is stored in the communication interface and remains after a power-off.

5.3 Modbus address selection

A Modbus slave on a Modbus network must have a unique address from 1-247. Address 0 is reserved for broadcasting and is not a valid slave address.

The Modbus address is selected via the menu system in the pump display.

5.4 Termination resistor

The termination resistor is fitted on the CIM 200 Modbus module and has a value of 150 Ω.

The CIM 200 has a DIP switch with two switches, SW1 and SW2, for cutting the termination resistor in and out. Figure 5 shows the DIP switches in cut-out state.

Fig. 5 Cutting the termination resistor in and out

DIP switch settings

Default setting: Termination resistor cut out.

5.5 Status LEDs

The CIM 200 Modbus module has two LEDs. See fig. 2.

• Red and green status LED1 for Modbus communication

• Red and green status LED2 for internal communication between the CIM 200 and the Grundfos product.

6. Modbus TCP, CIM 500 setup

6.1 Connecting the ethernet cable

Use RJ45 plugs and ethernet cable. Connect the cable shield to protective earth at both ends.

CIM 500 is designed for flexible network installation; the built-in two port switch makes it possible to daisy chain from product to product without the need of additional ethernet switches. The last product in the chain is only connected to one of the ethernet ports. Each ethernet port has its own MAC address.

Fig. 6 Example of Industrial Ethernet network

Fig. 7 Example of ethernet connection

6.2 Setting the Industrial Ethernet protocol

The CIM 500 ethernet module has a rotary switch for selection of the Industrial Ethernet protocol. See fig. 8.

Fig. 8 Selecting the Industrial Ethernet protocol

6.3 Setting up the IP addresses

The CIM 500 ethernet module is by default set to a fixed IP address. It is possible to change the IP address settings from the built-in webserver.

CAUTION

Electric shock

Minor or moderate personal injury- Connect CIM 500 only to SELV or SELV-E circuits.

It is important to connect cable shield to earth through earth clamp or to connect cable shield to earth in the connector.

8.4 GSM Real Time Clock

8.4.1 Explanation of event trigger

State

Control bits with a state event trigger behave like a ’state’ that is forced upon the DDA pump. CIM 200/500 will attempt to make the pump operate according to the ’requested’ state in the control registers 00101-00103. Due to certain state/mode restrictions, this might not always be possible (see explanation of the bit in question). The ’actual state’ of the pump can be read from the corresponding bit in the status registers 00201-00206.

Value change

Control bits/bytes with a value-change event trigger behave like a command that is executed when the bit/byte changes its value. CIM 200/500 will attempt to make the DDA pump operate according to the ’requested’ value in the control registers 00101-00103. The change will be reflected in the corresponding bit/byte in the status registers 00201-00206. Bits/bytes that are controlled by a ’value-change event trigger’ can be controlled from both Modbus and the pump HMI. The last value change, no matter from which source, will become active if not prevented by other conditions (see explanation of the bit/byte in question).

Rising edge

Control bits with a rising-edge event trigger behave like a command that is executed when a bit transition from "0" to "1" occurs.

8.5 Control registers

Modbus registers used for the control of the DDA pump.

8.5.1 Explanation of control bits in control registers

RemoteAccessReq

Control bit used by the CIM module to activate control from Modbus.

Deaerating

Control bit used to start and stop deaerating the pump.

If the pump has been stopped via the pump HMI (symbol ■ ), it is still possible to start and stop deaerating the pump from Modbus.

If deaerating of the pump has been started from Modbus, it can be stopped by pressing or on the pump.

AnalogMode

Control bit used to select type of analog input signal.

The toggling of this bit has no effect unless the pump is in operating mode "Analog". The actual state (readable from corresponding status bit) will be reset to 4-20 mA whenever another operating mode is selected.

TimerMode

Control bit used to select timer mode.

SlowMode

Control bit used to slow down the suction stroke velocity.

Velocity

Control bit used to select SlowMode suction stroke velocity.

The toggling of this bit has no effect unless the pump operates in SlowMode. The suction stroke will be reset to 50 % velocity whenever SlowMode is disabled.

AutoDeaeratingEnable

Data register 00319 OutputRelays, bit 2, will signal whenever automatic pump deaeration is active.

FlowControlEnable

When the FlowControl function is enabled, various faults and deviations related to the dosing process will be detected and indicated.

The enabling/disabling of FlowControl means the enabling/disabling of all alarms/warnings that are associated with flow measurement. See section 8.10 Measurement data modules.

If the FlowControl function is disabled, the AutoFlowAdapt function (see control bits AutoFlowAdaptEnable) cannot be enabled.

ModbusWatchdogEnable

The Modbus software watchdog is used to monitor the Modbus connection. If the connection is broken, the DDA pump will stop dosing and indicate a Modbus communication fault. See section 8.11 Alarms and warning.

When "Bus control" is selected via the pump HMI, the Modbus watchdog is automatically enabled every time the pump is powered on. If Modbus communication is somehow interrupted (no communication with a Modbus master), this will be detected and the DDA pump will stop with an alarm indicating "bus error" (event code 15).

Enabling of Modbus will at the same time automatically enable the monitoring of the cable connection from the E-box to the DDA pump (event code 152).

After power-on, the Modbus master can at any time control the enabling and disabling of the Modbus software watchdog. The monitoring of the E-box cable connection will follow this choice.

When "Bus control" is disabled via the pump HMI, the Modbus software watchdog is also automatically disabled and so is the monitoring of the E-box connection.

AutoFlowAdaptEnable

The AutoFlowAdapt function detects changes in various parameters and responds accordingly to keep the flow constant. Dosing accuracy is increased when this function is enabled.

The AutoFlowAdapt function can only be enabled if the FlowControl function is also enabled.

PulseMemoryEnable

The pulse memory function can be used in operating mode "Pulse". When it is enabled, up to 65000 unprocessed pulses can be saved for subsequent processing.

ResetFault

When this control bit is toggled 0 → 1, the pump will attempt to reset pending alarms and warnings and to restart the pump if it was stopped due to an alarm.

Pulse

When this control bit is toggled 0 → 1, a pulse signal is sent to the pump. This can be used in operating modes "Pulse" and "Batch" and is equivalent to a pulse signal from the signal inputs.

ResetVolumeCounter

When this control bit is toggled 0 → 1, VolumeTripCounter (module 30) is reset to "0".

SetRTC

When this control bit is toggled 0 → 1, the internal real-time clock (RTC) in the DDA pump will be updated. The values must have been previously written to the SetDataTime (registers 00116-00122).

8.5.2 Explanation of control mode

ManualIn this operating mode, the pump constantly doses the dosing flow set via SetpointManual (register 00106-00107) or the pump HMI.

1

PulseIn this operating mode, the pump doses the volume set via SetPulseVolume (register 00108-00109) or the pump HMI for each incoming pulse. Reception of the pulse command from Modbus has the same effect as an incoming contact pulse signal.If the pump receives more pulses than it can process at the maximum dosing flow, excess pulses will be ignored if the memory function (PulseMemoryEnable bit) is not enabled.

2

AnalogIn this operating mode, the pump doses according to the external analog signal. It can operate according to a 4-20 mA or 0-20 mA signal selected via the AnalogMode bit or the pump HMI.If the input value in analog mode 4-20 mA falls below 2 mA, an alarm will be displayed and the pump will stop.The relation between analog signal and dosing value is called analog scaling and must be set via the pump HMI.

3

TimerThe time the dosing should take place is controlled by a cyclic timer or by week timers. The selection is done via the TimerMode bit or the pump HMI. Some other parameters are related to timer dosing. They can only be programmed via the pump HMI.

4

BatchIn this operating mode, the pump doses the volume set via SetBatchDosingVolume (register 00110-00111) over a time period of SetBatchDosingTime (register 00112-00113) for each incoming pulse (or Modbus Pulse command). The remaining batch volume during dosing can be read from RemainingDosingVolume (register 00310-00311).

In case of a pump alarm or pump warning, the registers WarningCode and FaultCode will contain an event code for the cause of the problem.

The complete list of possible alarm/warning codes from a DDA pump is shown in the table below.

Alarm events will make the pump stop. Some of them require acknowledgement of the alarm before the pump can be restarted. This acknowledgement can come from the pump HMI or Modbus by using the ResetFault command in control register 00103.

The pump can only indicate one active alarm at a time, even when there are many simultaneously active warnings. The complete status of warnings can be read from the WarningBits register.

1) Warning or alarm is selected in the "Settings" menu via the pump HMI.2) An alarm only occurs when the ActModbusWatchdogEnable bit has been set.

See sections 8.5.1 Explanation of control bits in control registers and 8.9.1 Explanation of status bits.

9. Modbus RTU commissioning, step-by-step guides

9.1 Hardware setup, CIM 200

9.2 Modbus TCP communication setup, CIM 500

If the sensor configuration is changed, restart the CIM unit to ensure a correct scaling of the sensor value.

Step Action

1 Install CIM 200 in the Grundfos E-box according to the E-box documentation.

2 Select the Modbus slave address (1-247) using the pump HMI.

3 Select the transmission speed of the Modbus slave. See section 5.1 Setting the Modbus transmission speed.

4Select parity and stop bits of the Modbus slave (even parity with 1 stop bit or no parity with 2 stop bits). See section 5.2 Setting the parity.

5 If necessary, set line termination. See section 5.4 Termination resistor.

6 Connect the necessary cables from CIM 200 to the Modbus network.

7Confirm that the GENIbus LED is permanently green and that the Modbus LED is either off, if no master is actively polling the slave, or flashing green, indicating error-free communication. See section 5.5 Status LEDs.

The CIM 200 is now ready to be accessed via the Modbus network.

Step Action

1 Install CIM 500 in the Grundfos E-box according to the E-box documentation.

2 Select position 1 at the protocol rotary switch. See section 6.2 Setting the Industrial Ethernet protocol.

3 Power on the pump, and observe LED2 turn steady green and LED1 remaining off.

4 Connect one of the CIM 500 ethernet ports (RJ45) to a PC using an ethernet cable.

5Configure the PC ethernet port to the same subnetwork as CIM 500 (e.g. 192.168.1.1) and the subnet mask to 255.255.255.0. See section A.1 How to configure an IP address on your PC on page 34.

6Open your internet browser and make contact to the CIM 500 webserver.Factory default address: 192.168.1.100

7Log on to the webserver, factory default: User name: adminPassword: Grundfos

8 In the menu column to the left, select: Configuration > Real time ethernet protocol

9 Type in an IP address belonging to the same subnet as your PC (e.g. 192.168.1.2).

10 Type in the subnet mask 255.255.255.0, and leave the rest of the settings at their factory default values.

11 Click [Submit] to transfer the new settings, and close the web browser.

CIM 500 is now ready to be accessed from a Modbus TCP master via one of its ethernet ports. Use the IP address selected under step 9. The Modbus address (Unit ID) in the Modbus TCP telegram is not used. • The CIM 500 LED 1 will be flashing green when Modbus TCP communication takes place.• You can use the two ethernet ports to daisy chain CIM 500 modules.• It is possible to have connection to the webserver simultaneously with a connection to a Modbus TCP master.• It is possible to have connection to more Modbus TCP masters simultaneously, for example to have connection to PC Tool CIM while

connected to another Modbus TCP master.

10. Fault finding
10.1 CIM 200

You can detect faults in CIM 200 by observing the status of the two communication LEDs. See the table below and section 4. Specifications.

10.1.1 LED status

Fault (LED status) Possible cause Remedy

1. Both LED1 and LED2 remain off when the power supply is connected.

a) CIM 200 is fitted incorrectly in the Grundfos E-box.

Ensure that CIM 200 is fitted/connected correctly.

b) The cable from the E-box to the DDA pump is improperly connected or defective.

Check the cable connection between the E-box and DDA pump.

c) CIM 200 is defective. Replace CIM 200.

2. LED2 for internal communication is flashing red.

a) No internal communication between CIM 200 and the E-box to the DDA pump.

Check that CIM 200 is fitted correctly in the E-box and that the cable connection between the E-box and DDA pump is fitted correctly.

3. LED2 for internal communication is permanently red.

a) CIM 200 does not support the E-box connected.

Contact the nearest Grundfos company.

4. Modbus LED1 is permanently red. a) Fault in the CIM 200 Modbus configuration.

• Check the transmission speed (switches SW4 and SW5). If the switches are set to "software-defined", an invalid value may have been set via Modbus. Try one of the preselected transmission speeds, for example 19200 bits/s.

• Check that the Modbus address (switches SW6 and SW7) has a valid value [1-247].

5. Modbus LED1 is flashing red. a) Fault in the Modbus communication (fault in parity or cyclic redundancy check).

• Check the transmission speed (switches SW4 and SW5).See section 5.1 Setting the Modbus transmission speed.

• Check the parity setting (switch SW3). See section 5.2 Setting the parity.

• Check the cable connection between CIM 200 and the Modbus network.

• Check the termination resistor settings (switches SW1 and SW2).See section 5.4 Termination resistor.

10.1.2 CIM 200 Modbus communication faults

Fault Possible cause Remedy

1. The slave does not respond to telegrams.

a) Configuration or wiring error. • Check the visual diagnostics on the Modbus slave. Is the Grundfos GENIbus LED flashing green and the Modbus LED off or flashing green?

• Ensure that the cable between the Modbus master and the Modbus slave is connected correctly. See section 5. Modbus RTU, CIM 200 setup for wiring recommendations.

• Ensure that the slave address is configured correctly, and that the correct slave address is used in the Modbus master poll. See section 5.3 Modbus address selection for slave address selection.

• Ensure that the transmission speed and stop bit/parity settings are configured correctly in both master and slave.

• Ensure that each end of the Modbus trunk cable is terminated, if necessary. See section 5.4 Termination resistor for line termination of the Grundfos slave.

• Ensure that the bus topology for a Modbus network is correct.

b) The slave may be in listen-only mode. Either send a restart communications diagnostics command, or restart the DDA pump manually.

c) If the holding register of address 00001 "SlaveMinimumReplyDelay" is set too high, the master may time out before receiving the response from the slave.

Increase the timeout span in the master in order to communicate.

2. The slave responds with exception response 0x01: "Invalid function".

a) The master is trying to use an unsupported function in CIM 200.

See section 7. Modbus function code overview for supported function codes. Note that reading and writing coils is not supported, so only register functions and diagnostics will be valid.

3. The slave responds with exception response 0x02: "Invalid data address".

a) The master is trying to read or write an invalid data address. If a master tries to read register addresses that are not listed in the tables, the slave will respond with this exception response. Some masters may automatically try to read large blocks in one telegram, which will cause problems if some of the registers in the block are not supported. An example would be reading the CIM configuration and CIM status blocks in one telegram. This is not possible since there are unused addresses between the blocks.

• Avoid reading or writing invalid data addresses.• Ensure that register X is addressed as X - 1 in

Modbus telegrams, according to the Modbus standard.

b) The register address offset may have been changed from default.

Read the holding register at address 00002 "Register Offset" to see if this value is different from 0. If so, write the value 0 to this address to make the slave return to the default used in this functional profile.

4. The slave returns data value 0xFFFF (65535).

a) The value is unavailable. A data value of 0xFFFF does not necessarily indicate an error condition. It means that the value is unavailable from the DDA pump.

See section 8. Modbus register addresses for available data.

5. The slave does not change Modbus transmission speed with register 0004.

a) Configuration error. Set the transmission speed switches to "Software-defined". Otherwise, the value in register 0004 is ignored by the slave.

b) An invalid value may be set in register 00004. See section 5.1 Setting the Modbus transmission speed for invalid values, and set correct value in register 00004.

10.2 CIM 500

You can detect faults in CIM 500 by observing the status of the two communication LEDs. See the table below and section 4.3 CIM 500 Modbus TCP.

10.2.1 LED status

Fault (LED status) Possible cause Remedy

1. Both LED1 and LED2 remain off when the power supply is connected.

a) CIM 500 is fitted incorrectly in the Grundfos product.

Check that CIM 500 is fitted/connected correctly.

b) The cable from the E-box to the DDA pump is improperly connected or defective.

Check the cable connection between the E-box and DDA pump.

c) CIM 500 is defective. Replace CIM 500.

2. LED2 for internal communication is flashing red.

a) No internal communication between CIM 500 and the Grundfos product.

Check that CIM 500 is fitted correctly in the E-box and that the cable connection between the E-box and DDA pump is fitted correctly.

3. LED2 for internal communication is permanently red.

a) CIM 500 does not support the Grundfos product connected.

Contact the nearest Grundfos company.

4. Modbus LED1 is permanently red. a) Fault in CIM 500 Modbus TCP configuration.

Check that the rotary switch SW1 is set to 1.Check that Modbus TCP IP address configuration is correct.See section A.4 Modbus TCP configuration on page 35.

5. LED1 is permanently red and green at the same time.

a) Error in firmware download. Use the webserver to download the firmware again.

6. LED2 is permanently red and green at the same time.

a) Memory fault. Replace CIM 500.

10.2.2 CIM 500 Modbus TCP communication faults

Fault Possible cause Remedy

1. The slave does not respond to telegrams

a) Configuration or wiring error • Check the visual diagnostics on the Modbus slave. Normal conditions are that the Grundfos GENIbus LED2 is permanently green and that the Modbus TCP LED1 is off or flashing green. If not, see section 10.2.1 LED status.

• Ensure that the cable between the Modbus TCP master and the Modbus slave is connected correctly. See section 6.1 Connecting the ethernet cable.

• Ensure that the slave IP address is configured correctly and that the correct slave IP address is used in the Modbus master poll. See section 6.3 Setting up the IP addresses.

2. The slave responds with exception response 0x01 "Invalid function"

a) The master is trying to use an unsupported function in CIM 500.

See section 7. Modbus function code overview for supported function codes. Note that reading and writing coils is not supported, so only register functions and diagnostics will be valid.

3. The slave responds with exception response 0x02 "Invalid data address"

a) The master is trying to read or write an invalid data address. If a master tries to read register addresses that are not listed in the tables, the slave will respond with this exception response. Some masters may automatically try to read large blocks in one telegram, which will cause problems if some of the registers in the block are not supported. An example would be reading the CIM configuration and CIM status blocks in one telegram: this is not possible since there are unused addresses between the blocks.

Avoid reading or writing invalid data addresses. Ensure that a block of registers starting at address X is addressed as X - 1 in Modbus telegrams, according to the Modbus standard.

b) The register address offset may have been changed from default.

Read the holding register at address 00002 "Register Offset" to see if this value is different from 0. If so, write the value 0 to this address to make the slave return to the default used in this functional profile.

4. The slave returns data value 0xFFFF (65535)

a) The value is unavailable. A data value of 0xFFFF does not necessarily indicate an error condition. It means that the value is unavailable from the DDA pump.

See section 8. Modbus register addresses for available data.

5. The slave does not react to control actions or to writing of settings.

a) The DDA pump might be in "Local" mode, in which case Operating mode, Control mode and Setpoint cannot be changed from bus. Register 00201 bit 8 AccessMode must be "1" (= Remote) for bus control to be active.

Set the DDA pump in "Remote mode" by setting register 00101 bit 0 RemoteAccessReq to "1" (= Remote). The DDA pump should show "Controlled from bus" when status is read by Grundfos GO Remote.

Appendix 1

The appendix describes the parts of the CIM 500 webserver needed for the configuration of a Modbus TCP ethernet connection. For other CIM 500 webserver features not specifically related to Modbus TCP, see the installation and operating instructions for CIM 500.

A.1 How to configure an IP address on your PC

To connect a PC to CIM 500 via ethernet, the PC must be set up to use a fixed, static, IP address belonging to the same subnetwork as CIM 500.

Note that before you can acces the webserver, your PC must first be given an alternate IP address. If you have not already done this, follow the steps below:

Windows 10:

1. Click "Start".

2. Enter "Ethernet".

3. Select "Change adapter options".

4. Right-click "Ethernet".

5. Select "Properties".

6. Right-click "Internet protocol V4".


8. Select "Alternate configuration".

Windows 7:

1. Open "Control Panel".

2. Enter "Network and Sharing Center".

3. Select "Change adapter settings".

4. Right-click "Ethernet adapter".

5. Select "Local area connections".

6. Right-click "Internet protocol V4".


8. Select "Alternate configuration".

Key in IP address 192.168.1.10 and Subnet mask 255.255.255.0.

Fig. 1 Example from Windows 7

A.2 Webserver configuration

The built-in webserver is an easy and effective way to monitor the status of the CIM 500 module and configure the available functions and Industrial Ethernet protocols. The webserver also makes it possible to update the firmware of the CIM module and store or restore settings.

To establish a connection from a PC to CIM 500, proceed as follows:

Before configuration

• Check that the PC and CIM module are connected via an ethernet cable.

• Check that the PC ethernet port is set to the same network as the CIM module. For network configuration, see section A.1 How to configure an IP address on your PC.

To establish a connection from a PC to CIM 500 for the first time, the following steps are required:

1. Open a standard internet browser and type 192.168.1.100 in the URL address field.

2. Log in to the webserver.
