I’m writing a program with PLCNext Engineer using ladder logic. Every minute I would like to move a value to a new tag. With Rockwell software I would use the MOV command that is triggered after the TIMER.DN bit. How can I do the same thing with PLCNext Engineer. I tried the MOVE command in ladder logic but I cannot figure out how to have it run every minute. I would like to limit this to a single ladder routine.
Hello, Something like the below might work? This would be neater if the MOVE block had an ENABLE input, but I believe that this is coming in a future release of PLCnext Engineer. (of course the “RunTimer” variable must also be toggled every time the timer expires) ~ Martin
Hello Schmiddr,
some people do not like using “Return” in ladder so here is another example:
Instead of using Return you could also use a SEL Functionblock at the output of the move Functionblock and move the Sourcevalue to a “temp”-destination.
And once a minute, for one cycle you move it to the “real” destination for further processing.
kind regards,
Oliver
