3.8 Communication Devices screen
User access and Emails
The Communication devices screen shows a summary table of all the Communication Devices that have
been added. It also has tabs for:
• Email groups, which allows you to select which Email Groups receive an email if there is a com-
munication fault.
• User Groups, which allows you to select which Users have remote access to the communications
setting screens using the PV-Clinics monitor software.
You can double-click on a communications device for more details; this will take you to the next level of the
system tree.
Network size and complexity
Since Modbus is a polled protocol, each communications device will be subjected to reasonable traffic flows
regardless of the size of the PV Plant.
