A-B 1757-SRM

The Allen-Bradley 1757-SRM module is a system redundancy module provided by Rockwell Automation for its ControlLogix and ProcessLogix series PLCS. The main function of this module is to realize the redundancy backup of PLC system, so as to improve the reliability, availability and security of the system. When the main controller of the system fails, the redundant module can quickly take over the control and ensure the continuity of the production process.

Main function
Redundant backup: Realize dual-system hot backup of PLC system to improve system reliability.
Failover: When the primary controller fails, redundant modules automatically take over the control for seamless switchover.
Synchronization: Data is synchronized between the active and standby controllers to ensure system consistency.
Monitoring: Monitors the system status in real time to detect potential faults in time.
Main parameters and specifications
Model: 1757-SRM
Applications: ControlLogix and ProcessLogix systems
Function: System redundancy
Communication: Communication with the primary controller via ControlNet or Ethernet/IP

Indicator: Indicates the system status
Installation: Installed in the PLC chassis
