3. Project Description:
Subsequently networked Modicon 984-385 PLC with Modicon 984-145 PLCs over Modbus Plus. Operators are now able to monitor and control Trac Vacs via the Operator Interface. They are also able to schedule and sequence a series of Trac Vacs unattended operation.
Technology Components:
Reversed engineered monitor and control functions for Solids Handling at a Water Treatment Plant. System has an existing Modicon 984-385 and a Modicon Panel Mate Plus that serves as an Operator Interface for the PLC. Implemented closed loop PID controls and automatic pump start/stop alternation logic. Improved operational efficiency from 50% to 80%.
Modicon 984-385 PLCs, Modicon Panel Mate Plus, Modbus Plus networking, Modsoft PLC programming software.
