5.5.2 STATION SETUP(n:1)

The STATION SETUP, necessary for the n:1 (Multi-link) setup, checks whether
correct communications run with the connected GP System configuration.
NETWORK INFORMATION (DEV/ADR)
In the n:1 (multi-link) connection, the Network Information uses 2 words in its
correspondences. These two (2) words consist of a Connection List and a Valida-
tion List (described later in this section). These areas are allocated in the PLC's
Data Register (D) or Data Memory (DM). Adresses which can be allocated will
differ depending on the PLC type.

PLC Data Register
In the NETWORK INFORMATION ADR, setup the same address to all
the GP's connected to the same link unit. Furthermore, when there are
2 ports in the connected link unit, do not make them the same address.
u u u u u Connection List
The word address for the Connection List sets up the number of GP's connected to
the PLC, which must be registered beforehand on the PLC side. When these GP's
are connected to the PLC, the corresponding PLC bit numbers for the particular
GP Stations (see below) turn ON.
When the GP is connected to the PLC, and the option of GP only correspondence
ends and OFFLINE mode is entered, the GP Station Number then turns the corre-
sponding PLC bit OFF.
