CEX Bus terminator (TB850) failed on a running system
Dear Sirs, we have a critical system with a stand-alone AC800M controller (Compact Control Suite).
In this system there was a failure of a TB850 CEX Bus Terminator that was hard to identify.
The customer is asking the following questions regarding this module, and I can't find the answer to them in the documentation.
- Is this module active or passive?
- Which is the MTBF of this kind of module?
- Can the controller run without this termination module?
- How probable is that this kind of fault happens again?
I would appreciate any information that could help me answer to the customer.
Thank you and best regards,
