I have just noticed that the following example request is not possible using a single CA monitor or get request in CAv3: > "epics3://mypv?alarm+time+limits" There is no DBR-type that contains both the time-stamp and a limit range of any kind, so you would have to create this by combining two monitors with different types. It is now possible for the record to reprocess in between fetching the two objects, even though they're both kicked off by the same db_post_event() inside the IOC. I guess you can detect that by comparing the value fields you receive, but you'll have to decide what to do if they differ. - Andrew -- The best FOSS code is written to be read by other humans -- Harald Welte |
