Table 28 Communication options of the devices (max. possibilities)
The table specifies the maximum numbers of communication interfaces for the plug-in modules.
An external modem can be connected to RS232 communication lines (for details see 10.3.1)
i
The devices can operate up to two modems.
A combination of 1 internal modem and 1 external modem is allowed, or 2 external
modems connected to RS232 communication lines can be used.
i
All listed communication interfaces work independently and communication on
them can take place simultaneously and with the same priority.
Different communication speeds and different communication protocols can be set
for each interface.
ATTENTION!
Signals on all RS232/RS485 communication terminals of the device are
intrinsically safe. Common communication devices connected to the device
must be connected via a suitable communication barrier (B-RS).
The recommended wiring diagram is shown in Section 5.6.7.
The speed settings and communication protocol type for each interface can show on the device
