Hi all,
Recently started getting a few errors in our plant while commissioning. Some alarms are coming in related to the "Primary Cascade Port" being powered on, but not used for some of our CIOCs. All the ones with alarms coming in are fiber IOPs.
I managed to get rid of one by decommissioning a panel and recommissioning, but I can't decommission some of these panels because there is process running through their IO.
What would cause a fiber IOP to think it even has a cascade port? I checked the properties of the CIOC and everything is configured correctly.
How can I clear these errors without removing the panels from operation?
Thanks!
To follow up, we are still experiencing these errors on three of our CIOC panels that use fiber I/O Ports (Cascade not enabled in properties). Errors are as follows: 1 - Standby Secondary I/O Port Error - Standby Primary I/O Port Error - Primary Commissioning Module Error - Primary Cascade Port Error - Secondary Commissioning Module Error - Secondary Cascade Port Error 2&3 - Primary Cascade Port powered on but not used Could this be a potential hardware issue in the fiber I/O Port or the CIOC Carrier to make it think it has a copper I/O port with cascade capability? Or would it strictly be a commissioning error that would be resolved by decommissioning and commissioning again?
Edit: These CIOC panels were shop tested using a copper I/O Port, decommissioned and commissioned again at site using the fiber I/O port if that has any relevance. Thanks for any input. -Matt

Thanks for sharing that MPHymel. Enabling and disabling the cascade ports successfully cleared the "Primary Cascade Port powered on but not used" maintenance alarm on two of our panels. However, we still have the errors listed below on one panel. I suspect the fix will not be something that can be done online but will keep digging for a possible solution. - Standby Secondary I/O Port Error - Standby Primary I/O Port Error - Primary Commissioning Module Error - Primary Cascade Port Error - Secondary Commissioning Module Error - Secondary Cascade Port Error -Matt
