Hello everyone,

Here is my question:
I am using EVG-230 and EVR-230RF with the APS EPICS driver and i want to using the 'APS event receiver type' event record to trigger another record. I found that the event record can not be processed. I am using EPICS Base3.13.8 and vxWorks5.4.1. The following is my test db, but the calc record can not be processed.
record(event, "$(SUBSYS):$(DEVICE):event:gunT")
{
field(DESC, "")
field(ASG, "")
field(SCAN, "I/O Intr")
field(PINI, "NO")
field(PHAS, "0")
field(EVNT, "0")
field(TSE, "0")
field(TSEL, "0")
field(DTYP, "APS event receiver")
field(DISV, "0")
field(DISA, "0")
field(SDIS, "0")
field(DISS, "NO_ALARM")
field(PRIO, "LOW")
field(FLNK, "$(SUBSYS):$(DEVICE):calc:gunT PP MS")
field(INP, "#C$(ERslot) S36 @")
field(SIOL, "0")
field(SIML, "0")
field(SIMS, "NO_ALARM")
field(VAL, "36")
}

record(calc,"$(SUBSYS):$(DEVICE):calc:gunT") {
   field(PREC, "0")
   field(SCAN,"Passive")
   field(CALC, "(A<B)?(A+C):D")
   field(INPA, "$(SUBSYS):$(DEVICE):calc:gunT.VAL NPP MS")
   field(INPB, "100000")
   field(INPC, "1")
   field(INPD, "0")
}
In my test, EVG sends event code 36 to EVR and i can make sure that EVR has received this event code, because i can see the EVR FPS output from Oscilloscope. In erevent record, the VME field has set to Enabled.

The curious thing is that if i changed EPICS base to 3.14.9 with the mrfEventsystem driver, the "MRF Event Receiver" type event record can be processed.

What else can i do to figure out this problem.
