Data Link Precautions
Section 4-10
The data link table communications cycle time setting error registered in
the error log will contain the following information:
The value in the 2nd byte of the detail code for 021D registered in the error
history will be the minimum possible communications cycle time setting.
For example, if the communications cycle time is set to 5 ms, and the LNK
indicator starts flashing quickly, an error code of “021D 0512” will indicate
that the minimum possible communications cycle time setting is 18 ms
(12 Hex).
Adding Nodes
Be sure to consider the precautions listed below when adding a node to active
data links.
1,2,3...
1.
The node address of the node being added must be in the common link
parameters of the data links.
2.
Set data link tables in the node being added. This is not necessary, how-
ever, when using automatic settings with the startup node, although it is
necessary to include the node being added in the table of nodes participat-
ing in the data link in the automatic settings.
3.
The common link parameters for the node being added must be the same
as for the common link parameters already in operation. If the common link
parameters for the node being added are different from the common link
parameters already in operation, the node being added cannot participate
in the data link. Refer to the example below.
4.
If the communications cycle time for the data link tables is manually set
when a CS-series SYSMAC LINK Unit is to be added to the data links,
make sure that the value set is not below the minimum possible communi-
cations cycle time setting. For details of the values that can be set, refer to
the previous section,
