SYSTEM AREA READING
When using a Block Display Trend Graph, setup the Reading Area Size (in word units) to match the Trend
Graph's data size. Use this feature when you wish to allocate the Reading Area in the PLC Data Register (D),
or Data Memory (DM).
RESET ST ON WRITE DATA
Designates the mode which enables you to cancel the error from the error display when the Write error occurs.
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 ST 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 Validation List (described later in this section). These areas are
automatically allocated in the PLC's Data Register (D) or Data Memory (DM). The devices that can be allo-
cated will vary depending on the type of PLC.
• If you are not using the Reading Area, leave the 0 default values intact. This will allow you to
perform high speed data communication.

software)
• In the NETWORK INFORMATION ADR, setup the same address to all the ST's
connected to the same link unit. Furthermore, when there are 2 ports in the con-
nected link unit, do not make them the same address.
