ControlMaster CM10/CM30/CM50 Remote Setpoint Adjustment Technical Description

This technical description explains how to enable remote adjustment of a setpoint on ControlMaster CM10, CM30, and CM50 universal process controllers using digital signals and math block templates. It details the configuration of multiplexer math blocks to increment or decrement the setpoint via digital contacts, allowing operators to modify setpoints remotely when direct access to the controller is limited.
