Smart Process Control OMRON PLC-based
Process Control brings Major Innovations to Process Automation
● DCS functionality in a
PLC
Diversified Loop Control is even easier to use. Programming becomes even easier with function-block
● Analog Units with signal

Depending on the function block software
connections, all functions such as

Basic PID
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.
