IMC Operation


The Information Management Card serves as a communications/alarm interface. It contains a processor that manages communications between the two IOCs and the serial and Ethernet communications ports.

The  view shows the current status of the IMC, including the LEDs updated in real time, the internal card communication status, and highest active alarm severity.
