2.5.1 Connection of several units to a pLAN local network
If several units are installed serving one single location, they can be monitored, and their operating status
viewed, with one shared display whose network address is “32”.
The pCO boards in each unit must be interconnected in the pLAN local network using connector J11. Refer to
the manual of the pCO board for connection instructions.
2.5.2 Network component addressing
Each active network component is identified by its serial address. The I/O boards and the interface terminals
are active components.
The address of the I/O boards and of the 6-button PGD0 terminal is allocated following a dedicated software
procedure. Below are the addresses that need to be set up in boards and terminals.

It’s possible to link in local network up to 8 units, each one with its own private display and shared display.
If one “shared” terminal is used for all the units in the network, the address will be “32”. If the configured network
has 8 units and 8 terminals, one of the options below has to be selected:
all private terminals (one for each unit);
add max. 8 units to the network so that address 32 will be free for a shared terminal.
The main Menu screen appearing on the terminals shows the address of the connected board on the bottom
RH side.
If the unit configuration is such that an additional board is used as expansion board, the address for this will
be "2" for the unit 1, “4” for the unit 2, and so on.
