There is good information on the ECB201 Detail Displays and parameters in B0193ax2 Control Blocks Descriptions and B0700AH FBM230-233 User Guide. The User Guide also provides detailed description of the System Management display. I believe the parameter you listed is DEVSTS which indicates a System Alarm from the FBM (Byte 1 Bit 6). Look into the System Management Equipment Info Display for this ECB201 and see if it leads you anywhere. There are several Status Words to check. I am not an expert on all this, but may be a place to start.

The communication is working fine but the ECB201 shows a SYSTEM label in red in its detail display and the same block is in yellow in System Monitor. The omgetimp command on this parameter gives 0x00004801. I can't find what is wrong because everything looks ok but the alarm persists. Where should I start troubleshooting without rebooting the FBM?
