I am using the asyn module to write a device IOC. I want to set the SCAN field as Intr I/O to adapt to the application requirement.

The db file is like this:

 record(stringin,"$(P)Ver")

{

   field(DESC,"Firmware version")

   field(DTYP, "asynOctetRead")

   field(INP, "@asyn($(PORT),$(ADDR)) VERSION")

   field(SCAN,"I/O Intr")

}

record(stringin,"$(P)Mod")

{

   field(DESC,"Get counter mod")

   field(DTYP, "asynOctetRead")

   field(INP, "@asyn($(PORT),$(ADDR)) MOD")

   field(SCAN,"I/O Intr")

}

record(stringout,"$(P)Reboot")

{

    field(DESC,"Reboot Device")

    field(DTYP,"asynOctetWrite")

    field(OUT,"@asyn($(PORT),$(ADDR))REBOOT")

    field(VAL, "REST")

}

record(stringin, "$(P)GateInStatus")

{

    field(DESC,"DS:AlwaysON/EN:Need Input")

    field(DTYP,"asynOctetRead")

    field(INP,"@asyn($(PORT),$(ADDR)) GATEINSTATUS")

    field(SCAN,"I/O Intr")

}

record(longin,"$(P)Count07")

{

   field(DESC,"Counter 07")

   field(DTYP, "asynInt32")

   field(INP, "@asyn($(PORT),$(ADDR)) COUNT07")

   field(SCAN,"I/O Intr")

}

... ...

When I run the st.cmd file, it prompt: ”initCommon enum registerInterruptUser asynManager: getInterruptPvt Driver does not support interrupts on intterface asynEnum”.  All the test-error picture,  st.cmd and the complete .cpp files are attatched. I don't know where  the problem is and how to correct it.   Maybe  a polling function is necessary in the .cpp file when the SCAN filed is "I/O Intr", and the write or read functions should be called in the polling function?

Looking forward to your feedback.  Thank you very much.

Best wishes,
