Good Afternoon all,
I am fairly new to PLC equipment and have begun purchasing surplus equipment.
My question is regards to Siemens PLC equipment. On the labels they have numbers 1 - 10 written on and there is always one of these numbers crossed off.
My questions are:
1) What do these numbers signify
2) Does this mean that the parts are used if a number has been crossed off or is this crossed off at time of production by the factory?
Thanks,
Andy
