Computer Link Procedure - Panasonic FP2 ET-LAN Technical Manual

7.2 Computer Link Procedure

When computer link communication is being carried out on the programmable controller side, open
processing is used to specify the MEWTOCOL communication mode and to open the connection with
the partner node after initialization processing for the unit has been carried out. After a connection has
been opened with the partner node computer, there is no need to run a communication program on the
programmable controller side. Instead, the programmable controller receives command messages from
the computer, and automatically sends response messages back.
