6.5.2 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 corre-
spondences. These two (2) words consist of a Connection List and a Validation List
(described later in this section). These areas are automatically allocated in the PLC's
Data Register (D) or Data Memory (DM). Select the Device No in the , then enter the

cluded with screen creation software)
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.
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) should be turned on by the PLC.
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.
