1C31179G01 | Ovation/Westinghouse Remote I/O Master Attachment Unit

Overview

The Emerson 1C31179G01 appears in Ovation™ system documentation with conflicting primary classifications across verified industrial suppliers. It is variously described as a Remote I/O Master Unit and as a Controller Communication Processor with dual Ethernet ports. The specifications below consolidate all verified data points with conflict annotations.

Data Conflict Note: AutoModuleExpert lists this as a Remote I/O Master Unit managing communication to remote I/O drops. CSDN/Chinese industrial sources describe it as a Controller Communication Processor with dual 10/100 Mbps redundant Ethernet, supporting up to 64 concurrent clients. Both classifications agree it is a communication-intensive module within the Ovation architecture.

FAQ

Q: Is this a remote I/O module or an Ethernet processor?
A: Verified suppliers conflict. Some classify 1C31179G01 as a Remote I/O Master Unit; others as a dual-Ethernet Controller Communication Processor. Verify your exact part number and system BOM before ordering.

Q: What is the failover time for redundant Ethernet?
A: Per the communication processor classification, failover is <500 ms with real-time state synchronization.

Q: Can I replace this without shutting down the controller?
A: In redundant configurations, yes. Single-module replacement requires scheduled downtime.

Installation Guidelines

1. Verify the exact function of 1C31179G01 in your system architecture before installation.
2. Install in the appropriate Ovation controller rack or remote I/O chassis.
3. If using Ethernet functionality, connect redundant RLAN cables to independent switches.
4. Configure IP addresses and protocol settings via Ovation Workbench.

Selection Tips

• Do not order blindly. Confirm whether your system requires 1C31179G01 as a remote I/O master or as a communication processor.
• For remote I/O applications, verify distance and fiber/copper media requirements.
• For Ethernet processor applications, confirm RLAN VLAN isolation and firmware version compatibility.
