FP-X series
Another available application
When 17 or more FP-X units need to be linked, the use of Modbus in-
stead of MEWNET-W0 (see above) can accommodate up to 99 FP-X
units. Because each FP-X can be a master or a slave, a multi-master link
can be constructed by passing a token from a user program.
Token passing (by user program)
Multi-master link of up
to 99 units is possible.
PLC link (MEWNET-W0)
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.

Simple setting of the number of linked units, linked relays
and starting area address of the own station by using FPWINPro
allows contact information and data to be shared without program-
ming.
Baud rate of 115.2kbps, the highest rate for a compact model.
A transfer distance of 1200m, the longest distance for a
compact model.
FP-X and FP

Twisted-pair cable
FP-X requires a communication cassette (AFPX-COM3, AFPX-COM4 or AFPX-COM6)
FP2/FP2SH requires a multi-communication unit (FP2-MCU, FP2-CB485)

(Sigma) requires a communication cassette (FPG-COM3-A, FPG-COM4-A)
Different types of equipment need to be linked – FP-X flexibly meet such requirements.
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 control, etc.
Can also be used as
a slave station
