This document describes the components and procedures required to specify and deliver a simple consumption monitoring and reporting solution, using a Schneider Electric M221 PLC and AVReporter v3.0 or v4.0 software.
A special WAGES program is loaded into the M221 PLC using SoMachine Basic software. The special WAGES programs contain the application logic necessary to allow the PLC to convert pulses (via its digital input points) to enumerated WAGES measurements and places them into holding registers that can be read out via Modbus TCPIP protocol.
