Input Scaling for Live Tank Level Indication

Challenge

Tank level is already monitored by an analog sensor tied into a PLC, but there is no way for operators to monitor level directly at the tank.

Solution

A DXMR50-LB-MPA-PI Logic Block takes the analog signal representing the tank level from a T30R sensor on Input 2. The Logic Block scales the value and writes it to an SD50 Status Display over Modbus on Input 1. Set to Level Mode, the SD50 displays the tank level with LED fill, text, and threshold-based color indication. At the same time, the Logic Block recasts the analog signal on its Output back to the PLC, ensuring the existing monitoring system remains unchanged.
