No Message Blocks Available

Issue

Receive No Message Blocks Available when reloading or trying to access information on an Infinity controller.

Environment

  • Infinity controller
  • Errors
  • IO Bus
  • I/O Modules

Cause

No Message Block errors indicate a very busy IO bus.

Resolution

The controller is out of message buffers in the CX.  The only way out of it usually is to reload the CX

  • Check the DB to see if it’s correct offline
  • Then hopefully a CX reset and reload fixes it.
  • Might have to disconnect AC-1 if still an issue and commission 1 by 1 to get it back.
