    1.1 Features and Functions FP-series remote I/O system "MEWNET-F" is an I/O control network that supports the following features. I/O remote control with FP2/FP3 I/O information (On/Off information of contacts) can be exchanged between a CPU unit (master station) and an I/O terminal (slave station) at a remote location. A 2-conductor communication cable is used for the connection.
