Redundancy IOP Problem

Thread Starter

We have a Honeywell TDC3000 control system with redundant IOP. Problems that occur at this time where one of the backup (secondary) Analog Output IOP can not read by the main (primary) with a message in the System Satus for AO backup slot is CFG.

We've try to replace IOP AO backup and also validate the DB, then Replace Cable connection of IOP backup to the FTA's. But the problem still remains in the IOP AO backup with same massage CFG.

We would like to ask what the problem is and how the solution to the problem.

Thank you for your attention and response.

1. Is it CFG or "CFG MISMATCH" error?

2. Check and compare firmware of old IOP & new IOP.

3. What is the status of LED when you place the backup IOP in the slot?

1. That is CFG.

2. The firmware was same.
I try to placing the IOP to the other slot as redundant IOP and that is working well.

3. The LED status is red with showing blinking.
