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.
