1-21.1 Features and Functions of the UnitPowerful control capabilitiesAll of the functions of a mid-scale PLC are packed into the compact body size of the 32-pont type FP0. Aprogram capacity of 12k steps or 32k steps is provided as a standard feature, so you never have toworry about how much memory is left as you’re programming. In addition, 32k words are reserved fordata registers, so large volumes of data can be compiled and multiple operations can be processedwithout running out of memory.A full range of communication functionsUsing the Tool port (RS232C) provided as a standard feature on the main unit, communication can becarried out with a display panel or computer. Additionally, communication cassettes with RS232C andRS485 interfaces are available as an option. Installing a 2-channel RS232C type communicationcassette in the FPΣ makes it possible to connect two devices with RS232C port. A full lineup ofcommunication functions means you can also work with 1:N communication (up to 99 units) andPC(PLC) link function (up to 16 units).Controlling two devices with RS232C port with one FPΣWhen using the 2-channel RS232C type communication cassette1:N communication possible with up to 99 stations (units)When using the 1-channel RS485 type communication cassetteWhen using the 1-channel RS485 and 1-channel RS232C in combination
