Emerson IC695CMU310-DM PACSystems RX3i Max-ON Redundancy CPU
The release 6.00 execution of the RX3i Max-ON hot-standby redundancy CPU.
Product Overview
IC695CMU310-DM is a PACSystems RX3i Max-ON hot-standby redundancy CPU at firmware release 6.00.
This release added user-defined types, variable-indexed arrays, logic-driven write to flash and Backplane Operations Controller enhancements.
A replacement must be matched across both redundancy partners, firmware, project configuration and the complete synchronization path.
Performance
Coordinates hot-standby CPU redundancy across two approved RX3i systems.
Supports the release 6.00 program features identified for the DM execution.
Maintains controller state and failover behavior through the configured redundancy architecture.
Provides controlled project storage and logic-driven flash operations.

System Integration
- Back up both controllers, redundancy settings, network data, flash contents and application checksums.
- Record active and standby roles plus every redundancy-link and communications connection.
- Align firmware and hardware revisions before introducing a replacement into the pair.
- Test synchronization, controlled role transfer, I/O ownership, communications and recovery from the approved failure scenarios.
Applications
- Hot-standby redundancy in documented PACSystems RX3i Max-ON installations.
- Service replacement where the DM release identity must be retained.
- Lifecycle projects that preserve paired controller and application evidence.
FAQ
Q01What must match across an IC695CMU310-DM redundancy pair?+
Confirm exact CPU identity, firmware, hardware configuration, application checksum, redundancy settings, communications and any qualified companion modules.
Q02Can IC695CMU310-DM be mixed with a later IC695CMU310 revision?+
Do not assume mixed-revision operation. Use the approved Emerson release guidance and site qualification for the exact redundancy architecture.
Q03What backup should precede IC695CMU310-DM replacement?+
Save both controller projects, flash contents, variables, network settings, redundancy configuration, role record and diagnostics.
Q04How should IC695CMU310-DM failover be tested?+
Synchronize the pair, verify active and standby health, then perform the approved controlled role transfer while observing I/O, communications and process continuity.
Q05Why must firmware 6.00 remain visible in the IC695CMU310-DM record?+
The DM catalog execution is tied to release 6.00 features and behavior, so firmware identity is part of compatibility and recovery planning.
