Application Templates - ABB ControlMaster Series Manual

Application templates

To minimize commissioning time, the CM30 features up to 20 preconfigured control strategy templates. By selecting the required
control strategy, the template configures the CM30's function blocks and display automatically. Customization of the
preconfigured templates is also possible, providing the flexibility to create customized solutions.
Single loop
This template provides standard, single-loop process control and is available with or without a remote setpoint.
In this example, the temperature of a product heated by a heat exchanger is regulated via the control of the steam feed to the
heat exchanger.

Single loop with feed-forward
This template adds feed-forward functionality to the single-loop template and is available with or without a remote setpoint.
Feed-forward control enables the CM30 to anticipate, and respond to, process occurrences not yet detected by the process
variable signal.
In this example, the CM30 is regulating the speed of a dosing pump used to neutralize the pH of waste discharge. The flow rate
of the waste discharge is monitored and fed forward to the CM30 so that, as the flow rate increases, the speed of the dosing
pump increases automatically to neutralize the extra volume of waste discharge.
