Hey gang -
I can't seem to locate any decent sample code for accomplishing what i need to do.
I have a CompactLogix L23E, connected via ethernet to the rest of the network. I wish to poll the PLC and read various modbus registers, and i'm not having a great deal of success.
I have some sample code (Modbus_EZ_v2..) that makes it a Modbus Slave, but evidently only in the serial port(because I have to assign it a modbus address), and I need the ethernet port, as a distinct 485 network is coming into the serial port. I don't have a Prosoft card.
So, in one line, I'd like to read Local:*:I:* over Modbus via Ethernet.
Thanks for the push.
