Communications
6.21.1
Communications Settings
Chapter 5 (settings) explains the communications settings in detail and provides information
about the IED address, Baud rate, Stop bits, Parity of the rear port and Parity of the front
port. Other settings will be included when the communications protocol used (for example,
DNP3.0) requires them.
6.21.2
Communications Types
7IVD IEDs have two types of communication ports: always one RS232C type on the front, and
an optional port on the back. For the latter, you can choose between 1-mm glass or plastic
optical fiber, RS232C and RS485. The technical data about these communication links are in
Chapter 2 (Technical characteristics).
You can also have a second rear port for remote communications with protection, but you can
not configure digital inputs or outputs in this second rear port. The IED gives priority to the front
port over the rear port.
6.21.3
Communicating with the 7IVD
To communicate through these ports, use the ZIVercom® communications program, which
interrogates the IED's protection profile. The ZIVercom® program dialogs with the 7IVD family
and other equipment, either locally (through a PC connected to the front port) or remotely (via
the rear communications port) about all programming, settings, event recording, reports, etc.
The ZIVercom® communications program, which covers the protection profile, is passwordprotected against unauthorized users. The ZIVercom®, which runs under Windows™, is userfriendly. You use buttons or keys to open the various submenus.
Use the PROCOME or DNP 3.0 profile to communicate with the IED to request control changes
and to execute orders.
You can configure the remote communication ports only through the HMI. Note that the setting
for the front port is fixed at 4,800 bauds and 1 stop bit but you can select the parity in the
devices with rear port remote communications with protection as already indicated in Chapter 5.
7IVD models have two controllers, one for each remote communication port, so that you can
establish communication through both ports at the same time.
