Hi all,
I’m trying to get the attached logic working with MEDM and string-valued record fields and it isn't working. For the _expression_ "A = B", the text always appears, regardless if string A is different or the same as string
B. Do I need to do something special to make strings work with the MEDM calc functionality? Note that I'm using MEDM from EPICS WIN32 Extension Version 1.40.
The A and B string sizes are 18 characters.
Here is the text from the adl file.
text {
object {
x=320
y=205
width=180
height=14
}
"basic attribute" {
clr=20
}
"dynamic attribute" {
vis="calc"
calc="A = B"
chan="$(P)scan1.P1PV"
chanB="$(P)scan2.P1PV"
}
textix="ERROR: SAME MOTORS"
align="horiz. centered"
}
Thanks,
Jay Steele
