FPΣ
1.1 Features and Functions of the Unit
Powerful control capabilities
All of the functions of a mid - scale PLC are packed into the compact body size of the
32 - point type FP0. A program capacity of 12 k steps is provided as a standard feature,
so you never have to worry about how much memory is left as you're programming. In
addition, 32 k words are reserved for data registers, so large volumes of data can be
compiled and multiple operations can be processed without running out of memory.
A full range of communication functions
Using the Tool port (RS232C) provided as a standard feature on the main unit,
communication can be carried out with a display panel or computer. Additionally,
communication cassettes with RS232C and RS485 interfaces are available as an
option. Installing a 2 - channel RS232C type communication cassette in the FPΣ makes
it possible to connect two devices with RS232C port. A full lineup of communication
functions means you can also work with 1:N communication and PLC link function (up
to 16 units).
