Programming for a computer link
To use a computer link, a program should be created that enables command messages
to be sent and response messages to be received on the computer side. The PLC
automatically sends back a response to commands. No communication program is
required on the PLC side.
Also, if a software program such as PCWAY is used on the computer side, PLC data
can be easily compiled, without having to think about the MEWTOCOL-COM.
