Chapter 4. Modbus Applications
The ET-7000/PET-7000 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.
Most SCADA Supervisor Control And Data Acquisition and HMI software can easily
integrate serial devices via the Modbus protocol, such as Citect, ICONICS, iFIX, InduSoft,
Intouch, Entivity Studio, Entivity Live, Entivity VLC, Trace Mode, Wizcon, Wonderware,
etc.
