Chapter 4. Modbus Applications
The PET-7000/ET-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.
