19. 05. 2025

• USW version required: 3.62.0
• TDU version required: 1.4.5.0

PM compatibility: 1.41.0

New features

• Virtual events work the same on Modbus and M-Logic. The output of the virtual event will follow the input of the virtual event.
• Virtual toggles work the same on Modbus and M-Logic. If the input of the virtual toggle goes high, the output changes state once.
• Added parameter 7075, "Mains Fail Assumption", which enables the Mains controller to assume that the mains have just recovered at start-up, allowing it to run the OK timers.
• EIC: Keyswitch (#15050) is available for J1939 protocols.

• M-Logic virtual toggles (previously named switches) can now be read over Modbus.
• GENSET: If idle run was active, RMI oil pressure alarms would be active before it was detected that the engine was running. This has been changed so that the engine must be running before the alarms can be active.

Not UL approved version

PM compatibility: 1.24.1

Corrections:

• Island ramping when loadsharing over CAN or analogue line now works again.
