Section 1 Introduction Product Overview

Section 1 Introduction

1.1 Product OverviewAn S800 I/O station consists of a fieldbus communications interface (FCI) and up to 24 I/O modules divided in up to 8 clusters with a maximum of 12 modules in each cluster. The I/O station requires configuration data from a superior system, that is,a controller, in order to function.

CI840 is an FCI which acts as a DPV1 slave device on a PROFIBUS-DPV1 network, connecting S800 I/O modules to any controller with PROFIBUS-DPV1 master capabilities. This book describes the parameters and memory maps of CI840 and the I/O modules. Any configuration tool recommended for the master controller can be used to enter the required information.

For information on the CI840 hardware, refer to S800 I/O Fieldbus Communication Interface for PROFIBUS-DP/DPV1.

Section 2 Fieldbus Communication Interface CI840 General Functionality

Section 2 Fieldbus Communication InterfaceCI840

2.1 General FunctionalityThe CI840 fieldbus communication interface (FCI) transfers input values and diagnostics from the I/O modules to a superior controller, and transmits output and parameter values from the controller to the S800 I/O modules. It also performs signal conditioning on input and output values.

Communication with the superior controller (the PROFIBUS-DPV1 master) takes place via a PROFIBUS-DPV1 network, and communication with the I/O modules takes place via the S800 I/O ModuleBus. Some of the parameters received from the controller are intended for the FCI itself, and some affect a specific I/O module or an individual channel on the module.

An S800 I/O Station can consist of a base cluster and up to 7 additional I/O clusters. The base cluster consists of a single or redundant Fieldbus Communication Interface (FCI) module and up to 12 single I/O modules or 6 pairs of redundant I/O modules. I/O clusters 1 to 7 consist of a ModuleBus modem and up to 12 I/O modules. I/O clusters 1 to 7 are connected to the FCI through a fiber optic expansion of the ModuleBus. An S800 I/O Station can have up to 24 I/O modules, see Figure 2-1. For information on hardware, refer to S800 I/O Fieldbus Communication Interface for PROFIBUS-DP/DPV1, S800 I/O General Information and Installation and S800 I/O Modules and Terminal Units.

The FCI controls all operations of an S800 I/O station, acting as a pure slave station on PROFIBUS-DPV1 and as the bus-master on ModuleBus.

Due to the PROFIBUS-DPV1 specification it is not possible to connect 24 I/O modules, of all types, to one FCI. Please refer to information about limitations caused by PROFIBUS-DPV1 in Calculation of Maximum Number of Modules on CI840 on page 17.

Section 2 Fieldbus Communication Interface CI840Calculation of Maximum Number of Modules on

2.2 Calculation of Maximum Number of Modules on CI840In order to find out if a given configuration of analog and digital modules can be used, the following method should be used:

• Fill in number of modules in Table 2-1.

• Calculate the sum in the three columns:

– Sum User Parameters

– Sum Input Bytes

– Sum Output Bytes.

• Calculate the three total sums for:

– ParamSize

– InSize

– OutSize.

• Check that:

– ParamSize is less than or equal to 221 (220 if HCIR is used) in normal mode, 219 (218 if HCIR is used) in Extended HART mode

– InSize is less than or equal to 239 in normal mode, 199 in Extended HART mode.

– OutSize is less than or equal to 112 in normal mode, 90 in Extended HART mode.

If any of these three values is too high then the configuration can not be used.

Dynamic Data Exchange Section 2 Fieldbus Communication Interface CI840

2.3 Dynamic Data ExchangeFigure 2-2 gives an overview of how data is transferred back and forth betweenthe user application and the actual process.

The data transfer between PROFIBUS-DPV1 and the ModuleBus is not synchronized. Read and write operations are performed from and to a dual-port memory in the FCI. The ModuleBus data is scanned (read or written) cyclically, depending on the I/O module configuration. In one scan all digital modules, 1/4 of the fast analog modules and 1/10 of the slow analog modules are scanned. It takes 4 scans to read all fast analog modules and 10 scans to read all slow analog modules.

Figure 2-2 Dynamic Data Exchange

PROFIBUS-DP

Data exchange with PROFIBUS-DPV1 is cyclic and consists of both writing of data from master to FCI as well as reading data from FCI to master.

In the channel related diagnostic area for single I/O modules channel number 0 is used to point out a certain module. For redundant I/O module channel number 0 is used to point out pair of modules and channel number 63 for the backup module. Channel number 1 to n are used for specific channels within a module. All errors on modules are presented first in the device related diagnostic area and then errors per channel follows. The device related diagnostic area is truncated after 24 errors and then the Ext_Diag_Overflow flag (bit 7 in the third byte of the standard diagnostic information) is set.

3.1 General Parameter DefinitionsThe parameters for each I/O module comprise family, identity number and position on the PROFIBUS-DPV1 network, followed by a number of bytes specific for the module type. The specific parameters are listed and defined separately for each I/O module in the relevant section of this chapter.

Redundant I/O modules can only be placed in cluster 0. The position of the I/O module or a redundant pair is defined according to the table below.

A redundant pair of I/O modules can via Profibus only be addressed as a pair, not as separate modules.

General Memory Map Definitions Section 3 I/O Module Data

3.2 General Memory Map DefinitionsUnlike the static user parameter data, the memory maps contain changing information such as input/output values and diagnostics. Parameters required for immediate processing are also included, such as filter times for analog input values. Tables of memory maps for each I/O module can be found in the relevant section of this chapter.

Analog process values for standard voltage and current signals in memory maps are coded according to the table below.

Min. underrange is minimum guaranteed underrange but the underrange can be more dependent on type of I/O module.

Modules with for example input range 0 to 20 mA can sometimes show a small negative value if the input signal is negative.

Modules with for example input range -20 to 20 mA show value in the range -20 to 20 mA even if the specified signal range is 0 to 20 mA.

4.1 DPV1 servicesWith DPV1 services acyclic data can be read and written to a slave. CI840 supports two acyclic connections, for class 1 or class 2 masters.

The acyclic services have a service header of 4 byte, and up to 84 byte data block in normal mode and 251 byte in Extended HART mode. DDLM_Read and DDLM_Write are built up as described in DDLM_READ on page 155 and DDLM_WRITE on page 161.

In normal mode two DPV1 services are allowed, and in Extended HART only one.

READ DYNAMIC VALUE Section 4 DPV1 Services

4.2.5 READ DYNAMIC VALUE

With DPV1 service READ DYNAMIC VALUE the I/O module channel values and status can be read. See Section 3, I/O Module Data for each module.

The number of bytes to read depends of the I/O module type.

• For analog I/O modules, 2 bytes (1 word) channel value are read for each channel. The first byte is the most significant channel data byte and the second byte is the least significant channel data byte per channel.

The last byte(s) read by the service, is the channel status for each channel. For 1-8 channels modules 1 status byte is read. For 9-16 channels modules 2 bytes are read. The least significant bit in the status byte is the channel status for lowest numbered channel.

As an example, see Table 3-5 for AI801.

• For digital I/O modules, 1 byte per 8 channels is read. For 1-8 channels modules, 1 channel value byte is read. For 9-16 channels modules, 2 channel value bytes are read. The first byte is the channel values for channel 9-16 and the second byte is the channel values for channel 1-8. The least significant bit in the channel value byte is the channel value for lowest numbered channel.

The last byte(s) read by the service is the channel status for each channel. For 1-8 channels modules 1 status byte is read. For 9-16 channels modules 2 bytes are read. The first byte is the channel status for channel 9-16 and the second byte is the channel status for channel 1-8. The least significant bit in the status byte is the channel status for lowest numbered channel.

As an example, see Table 3-73 for DI801.

Section 5 HART Communication

5.1 System Architecture Figure 5-1 shows a typical system using S800 I/O modules with HART support. The I/O modules are connected to the FCI through the ModuleBus link. The FCI is the ModuleBus master and provides a fieldbus communication with the Controller. The I/O modules represent the system process interface and a node that bridges communication between HART instruments and the communication path starting from an engineering workplace where an HART configuring tool is running.

AI845/AO845 and AI895/AO895 are eight channels modules. Each channel corresponds to an HART loop, connecting one HART instrument to the module.

Section 5 HART Communication Functions

5.2 FunctionsThe HART communication in CI840 is based on PROFIBUS-DPV1 services DDLM_WRITE and DDLM_READ. The DDLM_WRITE and DDLM_READ services are using index 0x30 (see table 4-1 and table 4-2) to be identified as HART requests.

The DDLM_WRITE and DDLM_READ services are built up as described in DDLM_READ on page 155, and DDLM_WRITE on page 161. The data structure differs depending on if the HART instrument is connected to an AI845/AO845 (see AI845/AO845 HART Master on page 169) or an AI895/AO895 (see AI895/AO895 HART Master Device on page 174) I/O module. The maximum size of the HART frame structure is 64 byte in normal mode and 227 byte in Extended HART mode.

The HART functionality in AI845/AO845 and AI895/AO895 are implemented in two different ways:

• AI845/AO845 are HART Masters which means that the I/O modules communicates as Master with the connected HART instrument in the HART loop.

HART commands can only be addressed to connected HART instruments.

• AI895/AO895 are HART Master Devices which means that the I/O modules are HART units. Therefore it is possible to send HART commands addressed to the I/O module itself. The Master functionality of the I/O module means that the module communicates as Master with the connected HART instrument in the HART loop.

HART commands can therefore be sent, either to a connected HART instrument or right to the I/O module.

5.3 CommunicationThe data exchange consists of a number of write- and read requests to the I/O module via PROFIBUS-DPV1. Figure 5-3 and Figure 5-6 shows the communication sequence of each I/O module type. CI840 can handle up to 6 HART requests to different I/O modules at the same time.

5.6 AI895/AO895 HART Master Device

5.6.1 HART Command Data Structure

In AI895/AO895 there are two ways of sending commands to the HART device. The maximum allowed length is 64 byte in normal mode and 227 byte in Extended HART mode.

5.6.1.1 Pass-through Command

This is a command that contains a direct address to the field device and it is recognized by the module if the address matches the address of an instrument included in its instrument list. This command and the reply do not include the preambles that are added/removed by the module. The data structure for Pass-through command is built up as shown in Figure 5-4. For data structure definitions see Table 5-5.

5.6.1.2 Copy Command

This is a command addressed to the module. Its data field contains a command that must be transferred to the field device connected to a selected channel. Preambles are not included in the command destined to the field instrument and are added by the module before sending it to the device on a HART loop.

The whole command is sent to the loop indicated by the channel number.

The response from the field device is copied in the module reply without preambles.

Section 5 HART Communication Delayed Responses

5.6.4 Delayed Responses

When a Pass-through command or a Copy command requires too much time to be completed, a delayed responses mechanism is used. In the module one delayed buffer is reserved. This means that only one command from the configuring tool to a field slave device may be active at a time.

When a command is received and the buffer is in the state DR_EMPTY (buffer is available), it is stored into the buffer to be routed to the instrument it is addressed to. A reply containing the DR_INITIATE command response (error code 33) is sent to the configuring tool. The delayed buffer enters the DR_INITIATE state.

When the module to instrument command - reply is completed the response from the field device is stored and the delayed buffer enter the DR_DONE state. If the Mux to instruments dialog has a communication failure or a "no reply ", the delayed buffer enters the DR_DEAD state. If a communication error is detected, the reply is stored and the delayed buffer enters the DR_DONE state.

When a command is received and the buffer is not in the state EMPTY the module must verify if it matches a previous stored command.

If it matches:

• in the DR_DONE state, the module will reply with the stored reply coming from the instrument. The buffer will enter the DR_EMPTY state;

• in the DR_DEAD state, the module will reply with the DR_DEAD command response (error code 35). The buffer will enter the DR_EMPTY state;

• in the DR_INITIATE or DR_RUNNING state, the module will reply with the DR_RUNNING command response (error code 34). The buffer will enter the DR_RUNNING state.

If it does not match, the module will reply with a BUSY command response (error code 32). The buffer can be flushed with command 106.

Section 5 HART Communication Locate Instruments

5.6.8 Locate Instruments

The locate function permits the identification of field device connected to each channel. A Command #0 is sent to each device and data in the reply of Command #0 ("Read Unique Identifier") permit the determination of the device revision, the building of the Unique Identifier and of the transmitter's data list. The number of preamble characters required by the device is also determined. The command 0 is addressed to short address 0.

The transmitter data list includes the following items:

• Manufacturer identification code

• Manufacturer's device type code

• Device ID number

• Number of preambles required

• Universal command revision

• Device specific command revision

• Software revision

• Hardware revision

• Device function flag

The Locate function is performed by the module when it enters the OPERATIONAL STATE, when a reset command (42) is received. After entering the OPERATIONAL STATE an AO895 module waits 5s before starting the locate function.

During the locate function, the RESET bit (Operation in progress) is set. At the end of the locate function the RESET bit is cleared. During the locate function only commands 0, 11, 12, 13, 16, 48, 129 are accepted by the module. To other commands the module will reply with command error code 32 (busy).

A single loop can be rebuilt also when a rebuild channel command (154) is received. While a channel is been rebuilt (during the locate function or during a rebuild loop phase) the channel REBIULD bit and the module error status bit 4 (More status available) are set.

3BSE 025 251R4101 183

Scanning Function Section 5 HART Communication

5.6.9 Scanning Function

Process values are not carried via HART and analog process values are handled in the same way AI/AO 890 modules do.

The scanning function is implemented to monitor the presence of field instruments. When the scanning is enabled (with command 149) all instruments of the instruments list are scanned (a different channel every 5s) with HART command 1.

If an instrument does not reply the DISAPPEARED and SEARCHING bits related to that instrument are set. Then the module begins to scan that instrument with HART command 0.

If there is a reply to command 0, the module verifies if it comes from the original instrument:

• if it does, the APPEARED bit is set, the DISAPPEARED and SEARCHING bits are cleared and the module restarts the normal scanning activity.

• if it does not, the MISMATCHED bit is set, the DISAPPEARED bit is cleared and the module keeps on searching the instrument with command 0.

When a command 129 (Read channel status) or a command 160 (Read all channels scan status) is received, the DISAPPEARED and APPEARED bits are cleared.

Appendix C HART Addressing General

Appendix C HART Addressing

C.1 GeneralTo be able to communicate with a HART device, its HART address (5 bytes long) must be known. For AI845/AO845 and AI895/AO895, the address of connected HART instruments are read as follows:

• For AI845/AO845, HART command 0 (with 1 byte short address format) should be sent directly to the connected HART instrument. The HART instrument will respond with information that should be used to interpret its 5 bytes long address of the instrument, see How to Interpret the HART Address on page 213.

• For AI895/AO895, HART command 0 (with 1 byte short address format) should be sent to the I/O module itself. The I/O module will respond with information that should be used to interpret its 5 bytes long address of the I/O module, see How to Interpret the HART Address on page 213. To get the addresses of connected HART instruments, HART command 130 should be sent to the I/O module. The I/O module will respond with a list of connected instruments.

C.2 How to Interpret the HART AddressExtract the 5 bytes HART device address from command 0 response according to following:

Address Byte 1 = 2#10XX XXXX where XX XXXX is the 6 least significant bits of the Manufacturer identification code.

Address Byte 2 = Device type (16#EC for AI895 and 16#EB for AO895).

Address Byte 3-5 = Device identification number.

When command 130 is used the first byte in the received address must be adjusted in the same way as for address byte 1 in command 0.
