I have a legacy A2N-CPU utilizing a A1SJ7C24 serial communication module to exchange data to a VAX.
Can someone explain to me how I can access the data registers necessary to view the data in those registers that are being sent through the serial comms?
Also, how does this PLC convert these binary tables to ASCII? I cannot see any ladder logic that does this. I am using GX developer software.
