Major Features

1. Basic functions
[Up to 384 input/output points]
The number of input/output points (up to 256
points) wired directly to the PLC and remote
input/output points (up to 256 points) on the
network (CC-Link) can be increased to 384
points in total.

connected.)
[Program memory]
The PLC has a 64K-step RAM memory.
Use of the memory cassette enables the
program memory to be used as flash memory.
[Operation instructions]
Various instructions, such as floating-point and
character string processing instructions and
scaling instructions, are provided.
[Built-in RUN/STOP switch]
The PLC can be started and stopped with the
built-in switch.
RUN and STOP commands can be given to the
PLC through a general-purpose input terminal or
peripheral device.
