● Compolet
Communications
programming between
a PC and PLC can be
accomplished easily
with ActiveX control.
● NS Runtime
You can communicate
with the PLC using the
screen data created

CPU Unit
Duplex Process-control CPU
Unit can help reduce risk in
systems that must not stop.
● Process I/O Units
Analog I/O Units are available
for diverse functions such as
Isolators, power supplies, and
signal conversion.
PLC (CS Series)
● Loop Control Board/Unit
Condenses DCS functions in a
compact Unit and enables
function-block programming.
● CX-Process Tool
Function blocks can be pasted
into windows and graphic
programming can be
performed by arranging blocks
with the mouse.
Diversified Loop Control is even easier to use. Programming becomes even easier with function-block
programming.
Depending on the function block software
connections, all functions such as
operation block I/O combination
specification can be achieved using only
function blocks. Moreover, combining
function blocks makes possible a wide
array of control methods, from basic PID
control to cascade control, feed forward
control, and variable gain control.
