I'm not sure if it is relevant to this discussion, but It's worth noting
that this post concerns a different EPICS driver for the same Micro Research
Finland hardware. My mrfioc2 driver didn't exist in 2008.
As a matter of habit. Which versions of EPICS Base, devlib2, and mrfioc2 are you using?
Also, what hardware and OS are involved?

By this you mean that both EVR cards are cabled to the same EVG?
If so, I don't understand what you mean by 'event "19" is not
supposed to received by evr1'.
>For example, in test:evr1:Event-Wf, the event number is like this: event "38" is received twice and event "19" is not supposed to received by evr1. But when I monitored the value of test:evr1:EventCode and test:evr2:EventCode, their value is correct and received the event sequence which they should received. It is very weird.
Can you provide a more complete database? It is hard for me to judge how
test:evr1:Event-Wf work without seeing its definition.
> I do not know if there is some wrong with my waveform device support but since EventCode record can separate different EVR why Event-Wf record receives two EVR's event?

Can you also include the dbLoadRecords() lines?
