Hello everyone,
I am looking for Delta DVP communication protocol as well as the internal devices memory map (i.e communication addresses of registers) for DVP-SS2 and DVP-20PM. A document is available on delta's website regarding communication protocol which is invalid for newer PLCs, I have tested those addresses using serial port monitor.
There are numerous threads on sending password read request to the PLC such as:
3A 30 31 30 33 31 33 46 35 30 30 30 32 46 32 0D 0A
And PLC provides the pass in return. But this is invalid for new PLCs.
Can someone please guide me on this issue? Where can I get the memory map for Delta DVP SS2 and 20PM PLCs.
