hi guys
i have a question , i have two machines linked together via a msg instruction they are only using a couple of bits , what i would like to do is transfer an alarm bit to a hmi on the other machine could i use the unused bits to trigger the alarm, if so is it as easy as using the bit input to the other plc ??
on the msg instruction i understand that you enter a word address in the controller data table and the size of elements is the bits? please correct me if im wrong
and then you enter where the destination data table will be and ip address,
but how would i switch an alarm bit? i hope this makes sense
thanks stu
