5. Radio/Modem/PLC

Description
In addition to the GENIbus protocol, the G100 Radio/
Modem/PLC can communicate via the standard PLC
protocols COMLI and Modbus.
For all three protocols, direct connection (RS-232) or
connection via telephone modem or radio modem
can be used. The G100 usually functions as a slave
on the network.
When using direct connection or modem connection,
it is possible to multiplex the connection to the G100
(port 1, RS-232). This means that several G100 units
with different addresses can be connected to a sin-
gle serial port of a PC, when the appropriate equip-
ment is used, e.g. modem data splitter or radio
modems.
G100 address
When installing the G100, the physical bus address
must be set manually by the use of DIP switches on
the expansion board.
See section 5.1 Radio/Modem/PLC settings.

5.1 Radio/Modem/PLC settings

When the G100 is incorporated in a network together
with other G100 units, an address must be allocated
to each unit. Note that the address 0 is the "broad-
cast" address (default). All units will reply to this
address when asked.
The physical bus address must be set on the Radio/
Modem/PLC expansion board.
This should be done before start-up.

The G100 must be assigned a bus address which is
not already being used on the network.
