6. Modbus Applications
The PET-7H16M is a Modbus device that allows you to access terminals data via Ethernet and
communicates using a master-slave technique in which only one device (the master) can initiate
transactions (called queries). The other devices (slaves) respond by supplying the requested data
to the master, or by taking the action requested in the query.
