Setting Data Links
Section 5-2
Total number of words in data link send and receive areas of master
node =
Number of common send words in master node +
Number of individual send words in each node
×
Number of nodes par-
ticipating in data links (including both master nodes and slave nodes)
5.
The following values must be satisfied to ensure that the data link area is
fully contained within the specified area.
(Area start word
−
1) + (Total number of send and receive words of
master node *)
≤
6143 (when using the IR or CIO Area)
199 (when using LR Area)
32767 (when using DM or EM Area)
* Total number of send and receive words in master node =
Number of common send words in master node +
Number of delivery send words in master node
×
Number of nodes
participating in data links (including both master nodes and slave
nodes)
6.
If a node that does not actually exist (e.g., a node that is scheduled to be
added in the future) is registered as a node that will participate in the data
links, a data link area for that node will be allocated in the master node, and
the send/receive area will be refreshed with “0” data.
7.
Automatic data link creation with 1:N allocation can only be performed with
CS1W-CLK21-V1, CS1W-CLK23, CJ1W-CLK21-V1, CJ1W-CLK23,
3G8F7-CLK21-V1, and 3G8F7-CLK23-E Controller Link Units. If any other
model is used, the LNK LED will flash and it will not be possible to partici-
pate in the automatic creation with 1:N allocation.
8.
If automatic data link creation with 1:N allocation is to be set up using CX-
Net operations in the CX-Programmer, use CX-Programmer Version 3.2 or
higher. Setup cannot be performed using CX-Programmer Version 3.2 or
lower.
9.
The startup node (the node that sets the above DM parameter and starts
the data link) can be set at either a master node or a slave node.
10. When data links are automatically created for networks containing
C200HX/HG/HE PLCs, CS/CJ-series PLCs, CVM1, CV-series, and
CQM1H-series PLCs, the linkable area is restricted to the area of the
CVM1, CV-series, C200HX/HG/HE, or CQM1H-series PLC because it is
smaller than that of CS/CJ-series PLCs.
