i want interlock the program , if stopper not down condition run rework cycle .if stopper down condition run next auto cycle
kindly help me hoe to find stopper input /output signal macro variable
or how to assign these variables in ladder

[generaldisarray]

"stopper"? like , block delete switch "/"

/ M99P100 (M99 WITH P IS NON MACRO GOTO)
M30 (REWIND STOP)
N100
M99 (LOOP)

Or are you looking for external skip signal ?

Thanks for reply ,
stopper is Machine stopper ..where the component will butting..
this stopper operates by M code M52..

[generaldisarray]

So you are using M52 to activate some type of in-cycle part measurement device.
I have to assume that if you are willing and able to modify the ladder, you could just purchase part probing. Way more flexible.
