6.1.1 Communication Modes and Communication Ports
On the FP-X0, four different communication modes are available.
According to the communication mode to be used, the usable communication ports vary.
Communication mode
MEWTOCOL slave
Computer link
MEWTOCOL master
General-purpose serial communication
PC(PLC) link
MODBUS RTU
6.1.2 Computer Link
Computer link is used for communication with a computer connected to the PLC. Instructions
-
(command messages) are transmitted to the PLC, and the PLC responds (sends response messages)
based on the instructions received.
A proprietary MEWNET protocol called MEWTOCOL-COM is used to exchange data between the
-
computer and the PLC.
The PLC answers automatically to the commands received from the computer, so no program is
-
necessary on the PLC side in order to carry out communication.
6.1.3 General-purpose Serial Communication
With general-purpose serial communication, data can be sent back and forth between an external
-
device connected such as an image processing device and a bar code reader.
Reading and writing of data is done using a ladder program in the FP0R, while reading and writing of
-
data from an external is handled through the data registers.
