STATION SETUP, required with an n:1 (Multi-link) setup, checks whether data
communication is being performed correctly between the GP and the PLC.
NETWORK INFORMATION ADDRESS
With an n:1 (multi-link) connection, the Network Information setting uses 2 words
for its data. These two (2) words consist of a Connection List and a Validation
List (described later in this section). These areas are allocated in the PLC's Data
Register (D) or Data Memory (DM). Addresses which can be allocated will differ
depending on the PLC type.
GP-PRO/PBIII for Windows Device/PLC Connection Manual (in-
cluded with screen creation software)
For example, when 4 GP units— shown by bits 0, 2, 3, and 5—are connected,
002D (h) is written here.
In the NETWORK INFORMATION ADDRESS, setup the same address to
all the GP's connected to the same link unit. Also, when the link unit
has 2 ports, be sure they do not use 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 previously entered in the PLC. When these GP's are
connected to the PLC, the corresponding PLC bit number for each GP Station (see
below) turns 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.
