Programming
There is no programming required on the slave. Only the station number and the
communication parameters must be set in the system registers. The program for the master
side must send and receive commands according to the MEWTOCOL-COM protocol.
MEWTOCOL-COM contains the commands used to control and monitor the slave operation.
If a software program such as PCWAY is used on the computer side, PLC data can easily be
read and written without having to think about the MEWTOCOL-COM protocol.
8.5.5.1 1:1 Communication with Computer
For a 1:1 MEWTOCOL-COM connection between the FP Σ and a computer, an RS232C cable
is needed. Communication is performed via commands from the computer and responses
from the PLC.
