Communicating with the I/O Zone 583

WebCTRLWebCTRL is a web-based building automation system that includes communications with field devices like the I/O Zone 583 through a conventional web browser (such as Internet Explorer). A central WebCTRL server generates web pages containing device-specific information. In this way, the user can access status information and operating parameters for a single device, an entire building, or a network of facilities over the Internet, an intranet, or dial-up connection. For information on using WebCTRL, see the WebCTRL help file.

RS ProThe I/O Zone 583 supports the Rnet Sensor Pro (RS Pro) on the RS Pro port. The RS Pro is a thermistor-based temperature sensor designed for use with zone control modules. See Figure 2 for a diagram on how to connect the RS Pro to the I/O Zone 583.

Rotary Address SwitchesThe I/O Zone 583’s pair of rotary switches determines the I/O Zone 583’s MAC address when it is placed on a BACnet/ARC156 network. The rotary switches define the MAC address portion of the device’s BACnet address which is composed of the network address and the MAC address.

These rotary switches can be set to anything between 1 and 99. One switch corresponds to the tens digit and the other corresponds to the ones digit. For example, if the module’s address is one, set the tens switch to zero and the ones switch to one, as shown in Figure 6.

Figure 6. Rotary Address Switches

Listed By FCC Part 15 - Subpart B - Class A. Pending listings at the time of publishing this document: UL 916 (PAZX), cUL C22.2 No. 205-M1983 (PAZX7), CE (1997).

MountingScrew the I/O Zone 583 into an enclosed panel using the mounting holes provided on the cover plate. Be sure to leave about 2 inches (5 centimeters) on each side for wiring.

Power WiringCAUTION The I/O Zone 583 is a Class 2 device (less than 30VAC, 100VA maximum). Take appropriate isolation measures when mounting the I/O Zone 583 in a control panel where non-Class 2 devices (for example, 120VAC) or wiring are present.

You can power several devices from the same transformer if you maintain the same polarity.

The I/O Zone 583 has an operating range of 21.6VAC to 26.4VAC. If voltage measured at the I/O Zone 583’s power input terminals is


outside this range, the I/O Zone 583 may not work properly.

1. Turn the I/O Zone 583’s power off. This prevents the I/O Zone 583 from being powered up before the proper voltage is verified.

2. Make sure the 24VAC power source is off.

3. Connect the power wires to the I/O Zone 583’s power terminals labeled Ground and Hot (24VAC) (see Figure 1 on page 2 for location).

4. Apply power to the transformer.

5. Make sure that 24VAC is present at the I/O Zone 583’s power input terminals.

6. Set the I/O Zone 583’s address. Refer to “Rotary Address Switches” on page 4 for details about setting the address.

7. Turn the I/O Zone 583’s power switch on.

When the I/O Zone 583 turns on, the Power, Run and Error LEDs turn on and the Run and Error LEDs begin blinking. The Error LED then turns off. (See “LEDs” on page 14 for more information about LED signals.)


BACnet Networking

ARC156An ARCNET coprocessor allows the I/O Zone 583 to communicate on an ARC156 network through the CMnet port. ARC156 is a unique implementation of the industry standard, ARCNET. It differs from ARCNET as shown in Table 4.

The I/O Zone 583 uses the BACnet protocol to communicate with up to 99 other devices on the ARC156 network at 156 kbps. A special communications cable is recommended for maximum signal integrity. This cable can be ordered from:

Inputs and Outputs

InputsThe I/O Zone 583 is equipped with universal inputs that can accept both analog and digital input signals. Inputs 1 and 2 support thermistors, dry contacts, and 0-5VDC sensors. Inputs 3 through 6 support thermistors and dry contacts only.

The I/O Zone 583 uses voltage dividers and current sensing resistors to convert electric input signals to volts, which are then measured and converted to the appropriate units.

Input Signal TypesTable 5 describes the input signal types available on the I/O Zone 583.

Table 5. Input Signal Types

Signal Type Description

Thermistor Precon type 2 (10kohm at 77 deg F). Thermistor input voltages should range between 0.489V and 3.825V.

Dry Contact A 5VDC wetting voltage is used to detect contact position. This results in a 0.5mA maximum sense current when the contacts are closed. Any switch, which has more than 412 Ohms effective resistance (0.2V) when closed, must have an interposing mechanical relay when used with ALC modules.

0 to 5 VDC The output impedance of a 0 to 5VDC source must not exceed 10kohmx. The input impedance of the module is approximately 1Mohm.

Input Wiring RestrictionsWiring restrictions for the I/O Zone 583’s inputs are as follows:

• Maximum length: 50 feet (15 meters)

• Minimum gauge: 24 AWG

• Shielding: shielded and grounded to module’s Gnd terminal

Input Connection Sequence1. Turn the I/O Zone 583’s power off.

2. Connect the input wiring to the screw terminals on the module.

3. Ground shielded wire to the module's ground terminal.

4. Set the configuration jumper for inputs 1 and 2 to indicate signal type. Make sure the jumper is positioned correctly, and be sure to grip the jumper by the sides only. See Figure 4 on page 3.

5. Turn the module’s power on.

OutputsDigital outputs can be connected to a maximum of 24 Volts AC/DC. Each output is a dry contact (rated at 1A, 24VAC maximum).

Analog outputs can support voltage devices in the range of 0 to 10VDC. The device that is being controlled must have a minimum of 500 Ohms resistance measured from its input to ground and must share the same ground as the I/O Zone 583.

Digital Output Connection Sequence1. Turn the I/O Zone 583’s power off.

2. Connect the output wiring to the screw terminals on the module as shown in Figure 11 on page 11.

NOTE Do not power pilot relays from the same transformer that powers the module.

3. Verify each output's operation.

Lock the output to a known condition using the Equipment Definition's Properties page, then make sure the equipment operates as specified.

WebCTRL Configuration

You must configure protocol information on the Open Protocol Interface Properties page in WebCTRL (see Figure 13).

Open Protocol Interface

Base AddressUse the BACnet Device ID drop-down list to determine whether the I/O Zone 583’s BACnet Device ID will be autogenerated.

Not autogenerated The I/O Zone 583 uses the BACnet Device ID that was programmed in SiteBuilder.

Autogenerated The I/O Zone 583 uses the Base BACnet Device ID and the rotary address switches’ settings to determine

the BACnet Device ID. For example, if 240000 is entered in the Base BACnet Device ID field and the rotary address switches are set to one, then the BACnet Device ID is 240001.

You could change the BACnet Device ID by turning the I/O Zone 583’s power off, changing the rotary address switches, and turning the module back on.

Protocol Cross ReferenceThe Protocol Cross Reference tables allow you to define Modbus and N2 data addresses and cross reference them to BACnet objects in the GFBs. The parameters are defined on

the Open Protocol Interface Properties page.

Figure 13. Open Protocol Interface Properties Page


For example, BACnet analog input 1 (see Figure 14) references Modbus float value 30001 and N2 analog input 1 (see Figure 13 on page 12).

Figure 14. Sample GFB


Troubleshooting

Formatting the ModuleIf you are unable to communicate with the I/O Zone 583 after transferring memory, you can, as a last resort, manually format the module to try to restore communication. Formatting the module erases all memory, so you need to transfer memory back to the module once it is formatted.over the network segment.

NOTE Since the I/O Zone 583 is automatically formatted when you transfer memory, you should only manually format the module if communication was not established after the memory transfer.

1. Turn the I/O Zone 583’s power off. Make sure the module’s address switches are addressed correctly and are not set to ‘0 0’.

2. Set the Format jumper to cover both pins.

3. Turn the module’s power on.

4. The Error LED flashes three times in sync with the Run LED.

5. Remove the Format jumper.

6. Transfer memory to the module.

LEDsThe I/O Zone 583 has several LED indicators to show the status of certain functions.

Power - lights when power is being supplied to the module.

NOTE The I/O Zone 583 is protected by internal solid state Polyswitches on the incoming power and network connections. These Polyswitches are not replaceable and will reset themselves if the condition that caused the fault returns to normal.

Digital Output Status - lights when the digital output is activated.

Rx - lights when the module receives data from the network segment.

Tx - lights when the module transmits data over the network segment.

Run - lights based on module health. See Table 6 for explanation.

Error - lights based on module health. See

Table 6 for explanation.
