The Sentinel™ PRO remote monitoring system can interface with any water/wastewater processing equipment that uses a programmable logic controller (PLC) with Modbus sensors. The system monitors, delivers alarms and logs data input/output points from third-party Modbus sensors, transducers and PLCs. It supports Modbus RTU/485 and Modbus TCP. The system interacts with all existing sensors within a facility and provides operators with on-demand, real-time status and data acquisition from any Internet-connected device. Only one Sentinel PRO unit is required to monitor up to 64 Modbus registers or 12 different digital or analog status conditions at remote pump stations and tank farms.
