Hi Pavel,

I don't understand.  Do you want the record automatically to switch its value back to 0 after somebody sets it to 1?  Do you want the switch back to happen after some time interval?  If so, the bo record's HIGH field might do what you want.

Subject: [db] simple command ?

Hello tech-talkers,


I would like to implement a simple command record, the idea of which is to switch its VAL to 1 and then back to 0. Let's assume we have got the following record:

record (bo,"cmd:valve_trigger")
{
field(PINI, "YES")
field(DTYP, "S7plc")
field(OUT, "@plc/0 T=UINT8 B=0")
field(SCAN, "I/O Intr")
field(ONAM, "ONE")
field(ZNAM, "ZERO")
}

Is there any straightforward solution?
Thank you.
