    RF-TO-MODBUS KEY: RADIO RECEIVER FOR PLC

    A Newsteo sensor network can communicate with a RF-TO-MODBUS receiver wired to a programmable logic controller (PLC). This RF-TO-MODBUS Key gathers measurements from wireless loggers. Wireless loggers keep their standard functioning (periodically wake up and send measurements, alerts if sensor output values are beyond thresholds, and status information). These pieces of information are held in the RF-TO-MODBUS internal registers and can be queried at any time by the PLC. It is not necessary to bring the Newsteo radio protocol but only to integrate exchange tables.

    Settings of loggers (measurement frequency, alert thresholds ...) and RF-to-MODBUS key are done by radio, during the installation (using a PC, RF Monitor software and RF-to-USB Key). Once that phase is complete, the Modbus protocol between PLC and Modbus Key is sufficient for the operation of the facility. Several references of the Modbus key are available:

    RS232 or RS485
    IP30 or IP65
