The compact body can be equipped with up to three communication ports,
allowing for links to a wide variety of equipment.

PLC Link (MEWNET-W0)
With an AFPX-COM5 communication cassette (Ethernet type), FP-X data can be easily collected using a
host PC through a LAN. This cassette is also equipped with one RS232C channel, also facilitating data
collection from a tester (measuring instrument). This is an ideal Ethernet terminal for I/O control.
Bit data/word data can be shared (linked) among up to 16 FP-X
units. This is ideal for linking adjacent equipment in a distributed
control system.

Modbus-RTU* Compatibility
Compatible with both the master and slave of the Modbus* RTU, the world's de-facto standard.
Great performance is expected for air-conditioning, temperature controls etc.
* Protocol developed by the Modicon Inc. of the United States
●
Links with our other PLCs (FP

, FP2/FP2SH) are possible.
●
Simple setting of the number of linked units, linked relays, and
starting area address of the own station by using FPWIN GR/Pro
allows sharing of contact information and data without
programming.
●
The transfer rate of 115.2 kbps, the highest rate for a compact
model.
●
A transfer distance of 1200 m, the longest distance for a
compact model.

allow a change of the station number by
programming (SYS instruction).
Usable as a master station [F145 (SEND), F146 (RECV) commands]
Capable of easily communicating with a temperature controller, inverter, FP-e, and foreign PLC
Can also be used as
a slave station

Token passing (by user program)
With a communication cassette (two-channel type), FP-X can be equipped with up to three communication ports although
the body size is small.
The combination of RS232C, RS485, Ethernet, and USB interfaces enables communications with a variety of equipment.
The computer link provides command-response communications using Matsushita's open protocol "MEWTOCOL".
When the FP-X communication port is set to the computer link mode, FP-X, as a slave, automatically sends
responses to MEWTOCOL commands sent from a master station, such as a personal computer.
■
up to 3 communication ports
■
Computer link (MEWTOCOL slave)
General-purpose serial communications include the following two types.
1. FP-X, as a master, sends commands and receives responses in accordance with the protocol designated by the slave unit.
2. FP-X, as a slave, receives data sent from the master unit as is.

When 17 or more FP-X units need to be linked, the use of a Modbus
instead of a MEWNET-W0 (See following page.) can accommodate up to
99 FP-X units. Because each FP-X can be a master or slave, a multi-
master link can be constructed by passing a token from a user program.
