Setting Data Links
C200HX/HG/HE PLCs
Note a) The total number of words in data link send and receive areas
must not exceed 20,000 per node when using Controller Link
Units with unit Ver. 1.2 or later, or 12,000 words per node if using
pre-Ver. 1.2 Controller Link Units.
b) The following values must be satisfied for each node for the data
link area 1 and area 2 so that the final word in the data link does
not go beyond the last word in the PLC memory area.
(Data link start word – 1) + (Total number of send/receive
words in area 1 or area 2)
≤
c) Refer to the Controller Link Support Boards Operation Manual
(W307) for information on the Controller Link Support Board.
d) If CX-Net detects an error during the data link table check, trou-
bleshoot the error referring to 9-4 Troubleshooting Error Mes-
