Experimental Physics and
Industrial Control System

Hi Matthieu,

I stand corrected. It was copy-paste with few manual modifications that resulted in a mistake.

Nevertheless the INPA is not being incremented when calc record increments its VAL, even with FLNK added.

Thank you!

Best Regards,
Hinko

Hi Hinko,

its' not clear in your example how you produced a console trace for your
sub record, there is nothing obvious in your db example to make it process.

try add a FLNK, should work

 > record(calc, "$(user):subInc") {
 > field(SCAN, "1 second")
 > field(VAL, "0")
 > field(CALC, "(A+1)")
 > field(INPA, "$(user):subInc.VAL NPP")
   field(FLNK, "$(user):subExample")
 > }
