Dear Sirs,
I have what are supposed to be three identical machines, with interchangeable
parts . . Just the three machines get bigger.
They have Siemens PLC's in them, and they all have ET200S I/O blocks
in them.
The number one and number two machines have input modules with
Siemens 6ES7 131-4BD01-0AB0 in them. Number three has input modules
Siemens 6ES7 131-4BD01-0AA0. How much of a difference is that 0AA0
versus 0AB0 and are they interchangeable? (It looks like the 0AA0 modules
are very expensive and the 0AB0 modules are much cheaper.)
Also, while the input modules appear to be more available, the output
modules 6ES7 132-4BD01-0AA0 look like e-Bay might be the best
source of. Or is there a more readily available alternative?
Many Thanks,
Poet.
