Setting Data Link Tables Section 5-2
5-2-3 Advanced Data Link Settings
The order of link data bytes can be specified for each node according to the
needs of the connected device, eliminating the need for upper/lower byte con-
version (SWAP) processing in the ladder program or user application.
Note 1. The default status is sequential data (“sequential direction”) both for the lo-
cal node setup area and other node setup area. This is the same data or-
der used for the earlier CS1W-FLN02 and CS1W-FLN12 FL-net Units. Use
the default settings for normal use. When changing the data order, be sure
to consider the data order of the sending nodes and receiving nodes be-
fore changing the settings.
2. The data link data order can be set using the CX-FLnet or FL-net Unit Sup-
port Software Ver. 1.60.
3. The data link data order settings are enabled only for CS1W-FLN22 and
CJ1W-FLN22 FL-net Units. Settings are disabled for earlier CS1W-FLN02
and CS1W-FLN12 FL-net Units (always operate in sequential direction).

(default) Sends data in the order the same as the earlier CS1W-
FLN02/12 FL-net Units.
Reverse
direction Sends data from the local node setup area after swap-
ping the upper and lower bytes.
The upper/lower byte data of CS/CJ-series CPU Unit’s
data link area is swapped and changed in the Common
Memory.
Other node
setup area Sequential
direction
(default) Sends data in the order the same as the earlier CS1W-
FLN02/12 FL-net Units.
Reverse
direction Sends data from the other node setup area after swap-
ping the upper and lower bytes.
The upper/lower byte data of the Common Memory is
swapped and changed in the CS/CJ-series CPU Unit’s
data link area.
