Hello Yuliang,

I have deleted CP but It does not work. The PV "TimeStr" is still not updated.

Thanks, Adrián.

Hello Adrian,

 

Try to delete CP in line "field(TSEL, "$(Y):Timestamp_from_IOC1.TIME CP MS")".

 

Regards,

Yuliang

主题: Get timestamp from another IOC

Hello,

 

I'm trying to get the timestamp from another IOC (we will call it "IOC1") using the following DB records:

 

record(stringin, "$(user):TimeStr") {

    field(DTYP, "Soft Timestamp")
    field(TSEL, "$(Y):Timestamp_from_IOC1.TIME CP MS")
    field(INP, "@%s")
    field(SCAN, ".2 second")
}

record(ao, "$(user):Time"){
     field(DTYP, "asynInt32")
     field(OUT,  "@asyn($(PORT),$(ADDR),$(TIMEOUT))my_time")
}

record(calcout, "$(user):TimeCalc"){
     field(OUT, "$(user):Time PP")
     field(CALC, "A")
     field(INPA, "$(user):TimeStr.VAL CP MS")
     field(PINI, "YES")
}

 

At the startup of IOC2 I am able to get the timestamp from IOC1 but only once. The PV "TimeStr" doesn't update.

Can someone help me with this task?

 

Thanks in advance, Adrián.
