Hi Yu

I see. If there is an error msg, we should also be able to add an EPICS variable to monitor the status and trigger an alarm if this happens. Please check

Hi Zhenyu,

I don't see such a flag. But we do find these error messages when we look into the IOC log file.

drvModbusAsyn::doModbusIO port ADAM-6017-IN error calling writeRead, error=asynManager::queueLockPort queueRequest failed: port ADAM-6017 not connected, nwrite=32977344/6, nread=0

I will add this to the FST cooling manual, so next time when we have the same issue, we know what to do.

Best,

Yu

Hi Yu,

Thanks for the info. Does the controller provide some monitoring or status flag that we can use to monitor the status of the communication?

Dear All,

This is the follow-up email for the FST cooling system controlling issues we presented this morning.

We accessed STAR and power cycled the FST cooling crate, and the issue is fixed.

For more details, we found we lost the connection to the "ADAM-6017" controller, that's why we lost the readout for flow speed and so on. 

Another controller in the crate (ADAM-6052) is working fine, thus we can still control the chiller and pump. So it's not an IOC software issue.

Thanks to David, Tim, and Bill for the help.

Thank you.

Xu, and Yu
