1. Product Overview

The IC693DNM200 is a DeviceNet master (scanner) module designed for the GE Fanuc Series 90-30 PLC platform. It enables the PLC to act as a master on a DeviceNet network, managing up to 63 slave devices for real-time I/O data exchange and explicit messaging. The module is ODVA-compliant, supporting standard DeviceNet protocols for seamless integration with third-party industrial devices.

2. Key Features

• DeviceNet Master: Manages up to 63 slave nodes (e.g., I/O blocks, drives, sensors)

• Baud Rates: 125 kbps, 250 kbps, 500 kbps (standard DeviceNet speeds)

• I/O Connections: Supports 126 total I/O connections (2 per slave)

• Data Capacity: Up to 255 bytes input / 255 bytes output per slave; 3972 bytes explicit message data

• Isolation: 1500 VDC isolation between field network and PLC logic

• Service Port: RS-232 DB9 port for firmware updates and diagnostics

• Firmware: Field-upgradable via RS-232 port

• Compliance: ODVA, UL, CE, RoHS certified

5. Installation

5.1 Pre-Installation

1. Disconnect all power from the Series 90-30 rack and DeviceNet network.

2. Select target slot (main rack only, slots 2+; not for remote racks).

3. Verify backplane is undamaged and slot is empty.

5.2 Rack Installation

1. Align module with selected rack slot.

2. Insert firmly until backplane connector is fully seated.

3. Secure module with front-panel screws (torque 0.6–0.8 N·m).

4. Connect DeviceNet cable to 5-pin terminal block (follow polarity: V+, CAN_H, Shield, CAN_L, V–).

5. Restore power; verify PWR and MODULE OK LEDs illuminate.

5.3 Network Wiring

• Topology: Trunk-line with drop lines (max 63 nodes)

• Cable: Shielded 5-conductor DeviceNet cable (thick/thin gauge)

• Termination: 120 Ω resistors at both ends of trunk line

• Grounding: Shield grounded at one end only (to avoid ground loops)

6. Configuration

6.1 Software Requirements

• Proficy Machine Edition Logic Developer – PLC v3.0 SP1 Special 2+

• EDS Files: Required for slave device configuration (provided by vendor)

6.2 Basic Configuration Steps

1. In Machine Edition, navigate to I/O Configuration → Communication Modules.

2. Add IC693DNM200 to the project; assign a rack slot.

3. Configure DeviceNet Network Settings:

   • Set baud rate (125/250/500 kbps)

   • Set master node ID (0–63, unique)

4. Add slave devices (import EDS files); configure node IDs and I/O data sizes.

5. Map DeviceNet I/O data to PLC memory (%I, %Q, %AI, %AQ).

6. Download configuration to PLC; power-cycle module to apply settings.

7. Operation

7.1 Power-On Sequence

1. Apply power to rack; PWR LED lights.

2. Module runs self-test (MODULE OK blinks during test).

3. On successful test, MODULE OK solidifies; NET OK lights if network is connected.

4. Master initializes communication with slaves; I/O data updates begin.

7.2 Normal Operation

• I/O Scanning: Master polls slaves cyclically (configurable rate) for input/output data

• Explicit Messaging: Supports on-demand data exchange (e.g., parameter reads/writes)

• Slave Monitoring: Tracks slave status; logs timeouts or faults to PLC

7.3 Fault Handling

• Network Loss: NET OK off; master retries connection periodically

• Slave Timeout: ERROR blinks; PLC logs fault code

• Node Conflict: ERROR on; resolve duplicate node IDs

• Firmware Fault: MODULE OK off; reflash firmware via RS-232

8. Maintenance & Troubleshooting

8.1 Preventive Maintenance

• Monthly: Inspect LED status; clean connectors with lint-free cloth

• Quarterly: Tighten module screws and cable connections; check termination resistors

• Annual: Update firmware (if available); verify network integrity

8.2 Troubleshooting

9. Safety Precautions

• Electrical Hazard: Backplane and DeviceNet voltages can be lethal; disconnect power before servicing

• ESD Protection: Use anti-static wristband when handling module to avoid damage

• Network Isolation: Ensure DeviceNet network is isolated from high-voltage circuits

• Termination: Always use 120 Ω termination resistors to prevent signal reflection

• Firmware Updates: Follow instructions carefully to avoid bricking the module

10. Warranty & Support

• Warranty: 12 months from delivery (defects in materials and workmanship)

• Support: Contact Emerson Automation Solutions for technical assistance, repairs, or firmware updates
