NETWORK INFORMATION ADDRESS
With an n:1 (multi-link) connection, the Network Information setting uses two (2)
words — a Connection List and a Validation List (described in this section) — for
its data. 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.

NETWORK INFORMATION ADDRESS
, set up the same address to
all the GLCs connected to the same link unit. Also, when the link unit
has two ports, be sure they do not use the same address.
Connection List
The word address for the Connection List sets up the number of GLCs connected
to the PLC, which must have been entered previously in the PLC. When these
GLCs are connected to the PLC, the corresponding PLC bit number for each GLC
Station turns ON (see below).
When the GLC is connected to the PLC, and the option of
GLC-only correspondence ends and OFFLINE mode is en-
tered, the GLC Station Number then turns the corresponding
PLC bit OFF.
