General Information

MODBUS Automation Interface Module (Network Version)

The MODBUS Automation Interface Module provides a communications link between the Greengate lighting control network of panels and a system that uses the MODBUS Protocol. This allows a MODBUS based system to have the ability of turning On or Off relays or groups of relays within a Greengate lighting control system as well as get status from relays or switches. The MODBUS Automation Interface Module is custom configured for your job site’s needs as to what relays and groups it will control or monitor. The AIM unit supports the following MODBUS function codes:


3. All installation and service must be performed by qualified personnel or service technicians. 4. Install in accordance with the National Electrical Code and any other codes which may apply. 5. Installation and wiring information contained in this document is based on industry-accepted standards and practices. If conflicts exist between these instructions and any applicable codes or ordinances, please contact Cooper Controls before proceeding with the installation.

• Function Code 2: Read Input Status • Function Code 5: Force Single Coil • Function Code 15: Force Multiple Coils Before You Begin The MODBUS AIM ships without the motherboard installed in the enclosure unless the desired programming has been given to the factory prior to shipment. As each site is pre-configured, it will be necessary to provide technical support with the necessary programming information to ship the motherboard to the site. Please see the end of this document to obtain the paperwork that must be filled out for the configuration of this unit. The unit will be pre-configured for the protocol, baud rate and connection type for your site based on the information provided to us. A system integrator mapping table will be provided including a header for information on whether your unit has been set up for MODBUS RTU or ASCII protocol along with information on the two wire, four wire or serial connection and baud rate configured. Each MODBUS AIM unit has the capability of commanding and monitoring a total of 1200 points. Multiple MODBUS AIM units may be connected into a networked system if more than 1200 points are necessary. Please note that your AIM unit has been preconfigured for your site’s number of panels and desired points to command and monitor. Please refer to the systems integrator mapping table for the information on how the Modbus coils relate to the Greengate lighting control points. This document describes the installation process for the AIM unit. Questions should be referred to Cooper Controls Technical Support Department.

Getting Started 1. Do not discard these installation instructions. Please keep for future reference and operation information. 2. Use only as intended and at the listed voltage. Cooper Controls 203 Cooper Circle, Peachtree, GA 30269 800-553-3879

Figure 1: Automation Interface Module in Enclosure

Mounting the AIM Unit 1. Choose a dry location convenient to Greengate lighting control network that also has access to the MODBUS network. 2. Mount the enclosure on a firm surface using the predrilled mounting holes. 3. Low voltage network connections for the Greengate Network and the BACnet connection to the AIM enclosure should be done through conduit. Bring wiring in conduit through the left, top or upper right side. The lower right corner of the enclosure is reserved for the high-voltage power connection. 4. Remove all cuttings and dirt before providing power to the AIM unit.

Wi r i n g t h e A I M t o t h e G r e e n g a t e L i g h t i n g Network Wiring Notes 1. All low-voltage wiring is Class 2 wiring. 2. All low-voltage wiring must be run in separate conduit from

line-voltage wiring. 3. Test all low-voltage wiring for shorts to AC ground before connection to the AIM unit. 4. If using Belden 9841 or 82841 for the Greengate network connection, leave all shields disconnected making certain that shield is not exposed. 5. All panels and devices on the RS-485 lighting network should be daisy chained. Do not create a Star or T-tapped configuration. 6. Total network length should not exceed 4000 feet.

Wiring the AIM to the MODBUS System The AIM has been pre-configured to either a RS232, 2 wire 485 or 4 wire 485 connection per paperwork received from the site. Please install accordingly.

Wiring Notes 1. All low-voltage wiring is Class 2 wiring. 2. All low-voltage wiring must be run in separate conduit from line-voltage wiring. 3. Test all low-voltage wiring for shorts to AC ground before connection to the AIM unit. 4. Follow the manufacturer ‘s recommendations for wire type and distance limitations for your MODBUS system.

Table-1 Network Wiring Recommendations

Connecting the Greengate Network to the AIM 1. Disconnect power from the AIM. 2. Check the network wire for shorts and grounds prior to connection to the AIM network blocks. 3. Connect the lighting network wire to the Greengate Network + and - terminal block in the lower left corner of the AIM enclosure. These terminals are identified with labels Greengate Network + and Greengate Network -. Make certain to observe polarity. Connect the other end(s) of the network wire to the closest Lighting Controller (s). 4. The AIM has been sent to you pre-configured to be at the end of the Greengate network. A 100 ohm termination resistor has been pre-placed on the network wiring terminal block to terminate the network. If the unit is in the middle of the network, this termination resistor must be removed.

Figure 2: Greengate Network Wiring to the AIM Page 2

1. Disconnect power from the AIM. 2. Check all wiring for shorts and grounds prior to connection to the AIM MODBUS terminal blocks. 3. Connect the MODBUS connection to the 5 position terminal block on the right side of the AIM observing polarity. The casing of the AIM next to the terminal block is marked with the designations for each of the media type, i.e. 2 wire, 4 wire, or EIA-232. 4. It the AIM device is the last device on the MODBUS network, it may be necessary to add a termination resistor. Please refer to the MODBUS system’s manufacturer’s recommendations for the recommended resistor value to use in this circumstance.

Figure 3: Modbus Connection to the AIM

Powering the AIM Unit 1. Connect the neutral wire to the wire with the appropriate color coding for the voltage being used: White/Black=120VAC. 2. Connect the solid black wire to the dedicated branch circuit that is powering the transformer.

3. Module Status Indicator: This LED display in normal run condition will show a chase light that tracks around the outside of the display with a flashing red dot LED in the bottom right corner. If a number displays in this window, please contact Technical Support for further assistance. 4. Power indication LED.

Greengate Network Interface Board LEDs The Greengate Network Interface Module LEDs are located underneath the AIM unit and may be viewed from the left side of the module. The LEDs indicate the following:

Figure 4: AIM Power Components

LED indicator lights The AIM motherboard and the Greengate Interface board both have LED lights that can help with diagnostics. These are explained below.

AIM Unit LEDs The AIM unit has LEDs for diagnostics in several locations on the board. This includes the LEDs on the front casing of the AIM unit as well as some LEDs next to various ports on the board and an LED display that may indicate error codes. Please refer to the following drawing that indicates the location of the LEDs and their functions.

1. AIM Port S2 (Greengate Lighting Connection) Transmit and Receive LEDs. 2. AIM LED stack - the following LEDs are diagnostic indicators: Archive Valid - should be lit after a minute or two of the AIM being powered up. If this LED does not light up a few minutes after power up, please contact technical support. Port S1 TX and Port S1 RX - AIM port transmit and receive indicators for the MODBUS port.

DCD 232: Indicates, along with CTS 232, that the AIM has initialized the communication ports. RTS 232: Indicates, along with DTR 232, that the module is ready to send data. RX 232: Illuminates when the module is ready to transmit data to the AIM. TX 232: Illuminates when the module is ready to receive data from the AIM. RX 485: Illuminates when the module sends data on to the Greengate network. TX 485: Illuminates when the module receives data over the Greengate network. DCD 485: Data Carrier Detect for the Greengate Network. RTS 485: Request to Send for Greengate Network. STATUS: Unit functional status. Illuminates only if there is a hardware failure or software lockup. POWER: Remains illuminated while power is supplied to the module.
