Chapter 5 - Installation and Wiring
For example, when these 4 GP units—bit 0, bit 2, bit 3, bit 5—are connected,
002D (h) is written here.
• Be certain to setup this data before running.
• Turn all bits not related to the GP OFF.

Validation List
This area responds to the correspondence from each connected GP. In the Valida-
tion List, when the same bit numbers as the Connection List turn ON, the corre-
spondence is accepted. The Station Numbers of the communicating GPs turn their
corresponding PLC bit number ON.
If the correspondence between the GP and PLC is correct, the same value as in the
Connection List is written to the Validation List.
For example, the value 002D (h) in the Connection List, setup as the 0 bit, 2 bit, 3
bit, and 5 bit, writes to the Validation List.
• When the Connection List and Validation List do not match, a COM-
MUNICATION ERROR occurs. Check the setup again.
• When changing the connection, first turn all the bits OFF.
STATION NO. (0-15)
This is the setup for the GP Station Number mentioned above. The setup range is
from 0 to 15, and the only other restriction is the GP STATION NO. must be
unique in the system. If STATION NO.'s are repeated, a COMMUNICATION
ERROR occurs.
The STATION NO. is the number allocated to the particular GP unit. This number is
not related to the Link Unit Machine number.
