BTW, you probably don't want Strobe being used as part of the position calculation.
Strobe is used as part of the locking process and triggers the locking solenoid timing.
To calculate position, all you need are the Bits (A, B, C and D). You don't even need to use Parity, as it's sole purpose is to provide a basic value check.

I still have the PLC code to control a TOE80 using a Click PLC, but I no longer have the software installed to view it.
I'll try to test it. If it does not provide voltage, can I conclude that the encoder is faulty and needs replacement?

In regards to Strobe and Parity, If I understand correctly, I should remove Strobe and Parity to the position calculation (the PLC program I showed) right? Then, I will use Strobe for another rung for the locking process. Right? And I should completely remove Parity from the PLC program and disconnect Parity from wiring?

Too bad to hear about the PLC program of Click PLC. That would be a great resource to have in the next steps.
