How is the best way to toggle 2 bits in PLC
with one button in Wonderware?
Preferably without having to script it?
Thanks

No other way than scripting it..
Assume your using SP (based on previous posts..)
Perhaps cleanest way is to have a data change script, then to the toggle in the script, with last line making the second tag = the first.
But, as we seem to miss often, why the need to toggle 2x tags. ??

Assign Bit1 to a toggle pushbutton and write one line of code in the PLC to make Bit2 = Bit1.

Action script on button up..
Bit 1 = 1
Bit 2 = 2
Bit 1 = 1
Bit 2 = 2

Was I nuts on this...."Bit2 = 2"????
This is better route:
**********
If Bit 1 =1 THEN
Bit 1 = 0
Bit 2 = 1;
ELSE
IF Bit 1 = 0 THEN
Bit 1 = 1
Bit 2 = 0;
ENDIF;
ENDIF;
**********
This is a simple button script...
Is there a reason not use a script?

What do you do if both bits in plc = 0 or 1?

Maybe code should be:
IF <button> THEN
BIT1:= 1;
BIT2:= 0;
ELSE
BIT1:= 0;
BIT2:= 1;
END_IF

Both will just be inverted.
Now you are just setting bit 1 high as long as you keep the button pressed, and bit 2 high when you release it, what's the point of that?
Am I missing something or isn't it just a question of toggling two bits from one command?

That script would invert the two bits regardless of their original state. I understood the OP to be asking how to toggle two bits at once. I never got the impression that the OP wanted the two bits in question to always maintain opposite states.
Yeah, you are right with this. Sorry
