Computer
Communication Unit
-
Features
1. Connectable with operation display panel
Connection with an operation display panel that
supports our standard protocol (MEWTOCOL) is possible without any
communication program.
2. Economical peer-to-peer communication with
a computer is possible.
This unit can be directly connected with a
computer through RS232C to collect and write data from it without
building up a large-scale network.
3. One unit is equipped with two ports.
One unit is equipped with two RS232C interface
ports.
4. No communication program is needed on the
PLC. (Computer link function)
The PLC automatically returns responses using the
FP series' MEWTOCOL communication protocol so that there's no need
to prepare a communication program at the side of the PLC.
5. Connection with modem
It is possible to receive data over the telephone
lines from another PLC, by connecting modem with your PLC. (Only
the COM2 port and only reception.)
Regarding selection
Systems using the FP2 CPU unit connected with
multiple display panels and computers communication may be
hindered and not performed properly, depending on the location of
the port used for connection and the commands used.
Check the operating conditions in the manual and
select the units according to your applications.
