RCOM functions in accordance with the master-slave principle. The communication is
performed via point-to-point or multi-drop connection. You can also connect a dialing modem
on telecommunication authority lines. The modem must have command-initialized dialing and
an automatic reply function.
Redundancy is possible at different levels by optional duplication of communication boards,
modems and cables. Use redundant RCOM only for point-to-point connections.

MultiVendor Interface (MVI) is communication with other manufacturers’ control systems.
The following MVI protocols are available as standard:
•MODBUS
• Siemens 3964 (R)
• Allen-Bradley DF1.
In addition, there is an MVI free-programmable communication interface which you can use to
support user-defined protocols. This function enables you to connect “intelligent” transducers of
different types to an Advant Controller. The module used has two serial asynchronous channels
and is programmed in C language. The programming is done in a MVI Development
Environment based on a personal computer.
The module CI535 requires an older Development Environment based on a work station.
MVI uses a V24/RS-232-C asynchronous serial communication link. This link allows
communication at long distances.
