Panasonic FP-X Specifications page 12

Network
The compact body can be equipped with up to three communication ports,
allowing for links to a wide variety of equipment.
■ up to 3 communication ports
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.
■ Ethernet
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.
■ 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
Another available application
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.
