RE: motor record - how to turn off asyn error messages for a single motor

["Pearson, Matthew R. via Tech-talk" <tech-talk at aps.anl.gov>]

Hi,

 

Since the messages are coming from an Asyn driver, they are likely using the asynPrint function which uses a mask to control which messages are printed for that particular Asyn port. It’s possible to control this at the database level by using the asynRecord. If you load one of these and connect it to the Asyn port in question, you can use the trace control fields to turn off and on error messages:

 

https://epics.anl.gov/modules/soft/asyn/R4-38/asynRecord.html#TraceControlFields

 

Depending on the driver, you may need a separate record for each Asyn address.

 

Cheers,

Matt

Subject: [EXTERNAL] motor record - how to turn off asyn error messages for a single motor

 

Hello,

 

We use the asyn to communicate to motor controllers  in production user area, where motors may be unplugged due to the users need. For other application where we use asyn we use the SDIS/DISV field of a PV to set  an asyn device online/offline, thereby disabling messages from spewing to the console port. However, when the motor record is used, for a asyn motor controller it’s unclear how to turn off messages for a single device. Is there a method do this this, or is the only solution to shut  off all messages to the console port?

 

Regards,

-Kristi
