1-1-9 Application Examples
The Loop Controller can be used, for example, to build control systems capa-
ble of high-density monitoring of analog data through to advanced control of
instrumentation such as in the following four examples.
High-density Monitoring of Waterworks and Sewage Systems
Analog output signals
For example, 4 to 20 mA
Loop Controller

CX-Process Tool: Create function block data.
SCADA software: For example,
set SP, autotune PID constants,
and monitor PV.
