Help with messaging passing protocol between the OIT and GE Fanuc PLC.
The Maple Systems Operator Interface Terminal’s (OITs) message passing protocol allows the PLC programmer to choose between two different levels of implementation.
The first is a simple, no-handshaking message protocol intended for simpler operator interface applications; the second level adds full message handshaking between the OIT and the PLC.
Tech Note 1024, Message Protocol for the GE Fanuc PLCs describes how to use both levels of the message passing protocol, and describes the benefits and features of each level, and includes examples of ladder logic for the PLC to help illustrate the use of the OIT.
