Hello all,
A quick question. Can this PLC handle a custom RS-232 (or perhaps even RS485) protocol? I need to chop the incoming Bytes and process them individually to decode their values (Header, Address, Data0, Data2, .....Data31, & checksum byte) message blocks are always 35 bytes long. I see no way to do this with the existing port on the MicroLogix as I need it for Programming or to connect it back to the HMI at run time. Is there an add-on comm card available for the ML1100 that can communicate over RS-232 and allows me to chop up the bytes as needed? I also need to be able communicate both ways. (Send/Receive) Closest thing I can find is an ASCII card. Would this allow me to do what I am wanting to do here?
Thx.
