5. Radio Modem driver

5.1. General

The Master Generator has a built-in driver for control of an external Radio Modem, which can be used to cre-
ate wireless links where no cable is available in parts of an installation. One Master Generator must be defined
as the central MGEN and up to 32 Master Generators can be defined as remote MGEN's. The central MGEN
is continuously polling and updating the Dupline data from all remote MGEN's via the radio modem network,
and in this way it makes the entire system operate as one big Dupline network. Apart from increased reaction
time (depending on the number of remote MGEN's), the system will operate as if it was one Master Generator
connected to all the I/O-modules with cable. The Master Generator supports the Radio Modem type 2ASxE
and all 3AS types from the Finnish manufacturer SATEL (www.satel.fi). These are not supplied by Carlo
Gavazzi, but are available with local support worldwide. Find below an application diagram for the Radio
Modem option. Note: Analink modules cannot be used with Radio Modems.
The Radio Modem must be connected to the COM2 of the Master Generator. For serial cable pin connections,
please refer to the Master Generator datasheet. The baud rate selected for COM2 must correspond to the
baudrate used by the radio modems and the other master generators in the network.
The central MGEN must be defined for "Radio Modem central" function for COM2, while the remote MGEN's
must be defined as "Radio modem substation". The central MGEN can be configured for the usual intelligent
functions, and it can also be connected via COM1 or the RS485 port to a PLC or PC. The remote MGEN's,
however, cannot be configured for any intelligent function. They will simply operate as Radio Modem inter-
faces. The system can handle all types of digital, analog (incl. multiplexed) and counter values, except for
Analink values. The configuration of the Radio Modem function is performed in the menu "Edit" under "Com-
munication setup".
