The CPU entered STOP mode due to the CM CANopen module.

As shown in the attached image, the CPU unexpectedly went into STOP mode without the ERROR LED lighting up. Even after resetting the CPU power, it remains in STOP mode. To investigate the cause, I forcibly disconnected the CM CANopen module while the power was on. The same error code appeared, but this time the ERROR LED did light up. After reconnecting the module and resetting the CPU power, the CPU returned to RUN mode normally.

The Siemens forum mentions that similar cases were resolved through firmware updates. Has new firmware for the CM CANopen module been released?

  Hi ghkdehddnr, 

  I created a support ticket for this request, so one of the product experts should be reaching out to you about this.
