Emerson / GE Fanuc IC695PBM300-EC PACSystems RX3i PROFIBUS DP Master Module
An RX3i PROFIBUS DP master module carrying the exact EC-labeled hardware identity.
Product Overview
Emerson / GE Fanuc IC695PBM300-EC is a PACSystems RX3i PROFIBUS DP Master Module identified by the complete submitted catalog string. The suffix and revision characters remain part of the supply identity.
Selection of IC695PBM300-EC should follow the installed label, rack or controller record, field wiring and the verified technical details below; a neighboring family number is not treated as interchangeable.
Technical Register
Operating Features
The module provides PROFIBUS master control for configured DP slave stations.
The master project holds the station topology, addresses, data maps and device-specific GSD selections.
COMMREQ behavior is firmware-dependent and must be reviewed with the installed application.
The EC suffix remains visible because the manufacturer product page identifies the base module without decoding this release label.
Applications
- RX3i controllers acting as the central PROFIBUS DP master.
- Service of an installed network where the master configuration and slave documentation are available.
- Applications using configured cyclic I/O and approved acyclic or diagnostic exchanges.
Service Control
- Archive the controller and PROFIBUS master projects, GSD files and station list.
- Record module firmware, EC label, bus address, baud rate, connector, termination and segment layout.
- Compare CPU firmware and COMMREQ logic with the replacement module release.
- Verify every slave, cyclic data map, diagnostic message and controlled output state after startup.
FAQ
Why is the EC suffix retained for IC695PBM300-EC?
The suffix appears on the submitted hardware identity but is not decoded by the official base-module page, so it must remain on the order and compatibility record.
What files are needed before replacing IC695PBM300-EC?
Retain the RX3i project, PROFIBUS master configuration, all GSD files, station addresses and mapped data lengths.
Can IC695PBM300-EC be commissioned by matching only the bus address?
No. Baud rate, topology, termination, module firmware, slave definitions and host logic must also agree.
Why should COMMREQ logic be reviewed for IC695PBM300-EC?
The manufacturer documents a change in busy handling for later module releases, which can affect application sequencing.
What proves IC695PBM300-EC is ready for service?
Confirm every configured slave, cyclic I/O, diagnostics, applicable acyclic services and the safe response to a bus interruption.
