Operating cycle consists of a series of operations that are performed sequentially and repeated. To understand how a MSG instruction functions it is important that one has a good understanding of: When the processor communicates How the MSG instruction functions What a buffer is and how many are available Each controller family does operate differently FRN has increased and improved things from rev to revġ2 Understanding MSG Instruction When do the Processors Communicate Other things that can be accomplished with the MSG instruction: Share data to/from a third party controllers (CIP Generic) Get status information from processor or I/O modules The MSG instruction can be used to pass data from one Controller Family to another even if they are on different networks (a bridge is required):ĩ MSG Instruction What Other Things Can We Do The MSG instruction can be used to pass data from controller to another: The MSG instruction can be used to pass data from one controller family to another: The MSG instruction is not limited to a particular controller family!Ĩ MSG Instruction What Can Be Done (Advanced)
