Hey i was wondering if someone can help me with delays in PLC ladders it is for moving an arm i need it to delay for 3 seconds and the co-ordinates 002 004 006 please help
 
Big Dog,

You didn't give any usefull info - PLC and all input output units with model nimbers are needed.

I assume you need to pause/delay/wait for 3 seconds after arriving at your stated X,Y,Z position. If so, add arun after ALL positions are met to start a timer with the required delay, IE 3 seconds

If you are doing a delay repeatedly after your moves, it might be easier to set up a dwell (timer) either in a subroutine or, if you are using an AD plc, via stage programming. Would save on # of rungs in your program...
