● Process I/O Units
Function blocks can be pasted
Analog I/O Units are available into windows and graphic

Diversified Loop Control is even easier to use. Programming becomes even easier with function-block
programming.

Depending on the function block software Example: Cascade Control (Heating and Cooling)
connections, all functions such as

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.
