Manual Generation of Data Link Tables
It is possible to transfer the common link parameters from the node to which the
CVSS is connected to all the nodes designated by the CVSS.
Parameter
Communications cycle
time
No. of nodes in data link
and their node numbers
No. of LR words*
transmitted by each node
No. of DM words*
transmitted by each node
Note 1. *When combining CV-series PCs in data links with C-series PCs, LR 00 to
LR 63 in the C-series PCs correspond to CIO 1000 to CIO 1063 in the CV-
series PCs and DM 0000 to DM 0127 correspond to D00000 to D00127.
2. When combining C1000H-SLK11/SLK21-V1 or C200HW-SLK14/24 Units
with C200HW-SLK13/23 Units, all of the C200HW-SLK13/23 Units in the
data link must be within the last 918 words in the data link area.
CVSS
Description
The data link communications time between 5 and
255 ms. The communications cycle time will be self-
generating if not specified.
This information is set automatically when the No. of LR
words and No. of DM words parameters (see below)
are entered.
The number of LR words transmitted by each node
1 to 64: 1 to 64 words
-: Not part of data link
0: Can read LR words from other nodes only.
The number of DM words transmitted by each node
1 to 254: 1 to 254 words
-: Not part of data link
0: Can read DM words from other nodes only.
