Doesn't this PLC have Modbus RTU? In which case you can use the Modbus nodes.

That one's gonna be tough. GE, from what I remember, uses a proprietary protocol which will make finding any documents on it improbable. The only thing I've been able to use to talk to them, other than native programming software, was an OPC server like Kepware or Matrikon. Unfortunately they are paid products the make using it for personal use impractical. Although they are free downloads and run unlimited for 2hrs and then have to be restarted so you can maybe sniff the packets?
