Starting and Stopping Data Links
Section 5-3
Data Link Areas
Note
1.
Node 1 is the master node.
2.
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.
5-3
Starting and Stopping Data Links
Data link must be started after data link areas have been created. Use any of
the methods described below for the startup node to start and stop data links.
(The procedure for stopping data links is performed on participating nodes.)
These methods are the same for both manually and automatically set data
links.
Note
The data link mode (manual setting or automatic setting) and data link method
are determined according to the data link setting in the startup node. In the
startup node, set a data link table in the case of manual setting and data link
automatic setting parameters in the case of automatic setting. If the settings
are incorrect, the data link will not start.
!Caution
Check the following items before starting data links. If incorrect data link
tables or parameters are set, injury may result due to unexpected operation of
the system. Even if the correct data link tables and parameters have been set,
do not start or stop data links before verifying that there will be no adverse
influence on the system.
•
Manually Set Data Links
Check the data link tables in each node participating in the data link to see
that they are correct.
Be sure that data link tables are deleted from nodes that are not participating
in the data links.
•
Automatically Set Data Links
Be sure that the correct DM parameters have been set in the data link startup
node.
