New Features:

Nothing known

Enhancements:

• The 1756-CN2, 1756-CN2R, 1756-CN2RXT, and 1756-CN2RK modules are available with firmware revision 25.005.
• 1756-EN2F/C modules now have firmware revision 10.009 in the enhanced redundancy bundle.
• 1756-CN2/C support with firmware revision 20.055_kit4 is included.
• The 1756-RM2 and 1756-RM2XT modules utilize firmware revision 20.005.
• The Redundancy Module Configuration Tool (RMCT) has been updated to version 8.02.01.

Fixed Bugs:

• Resolved issue: Cycle Power to Unit no longer asserts in CnetSchedTransmitList.cpp Line 258 for channel faults (Late clock lock). Rack-optimized outputs now transition correctly.

Open Issues:

• Multiple switchovers can cause connection failure to SoftLogix controllers.
• Connections may drop temporarily if a 1756-EN2Tx communication module is not configured correctly.
• Redundant chassis synchronization fails when the controller nears its connection limit.
• Alarms scanned during the continuous task can be published to the alarm server twice after a switchover.
• Alarm status messages may be duplicated in the Alarm History Log after a switchover.
