2. Set data link tables for the PT side on the NS-Designer
The two setting methods below can be used. Use the appropriate method for the applica-
tion.
1) Specifying data link tables with NS-Designer:
If the data link tables are set from the NS-Designer, then they cannot be changed via
a network. Even if they are temporarily changed from the CX-Server or Controller Link
Support Software, they will return to the tables set from the NS-Designer the next time
the PT is started. To change the data link tables when they have been set from the
NS-Designer, it is necessary to retransfer the project or setting file to the PT.
Select Setting - System Setting on the NS-Designer, click the Controller Link Tab,
and specify the data link tables created in step 1. Refer to Section 7 System Settings
in the NS-Designer Operation Manual, for specifying the data link table file.
2) Setting data link tables across a network:
To do so, transfer the data link tables in the Controller Link Interface Unit from the CX-
Server or Controller Link Support Software, and do not specify data link tables from
the NS-Designer. If data link tables are set via a network, then they can later be
changed via a network as required. For details on the transfer method, refer to the
CX-Net Operation Manual (W361) and the Controller Link Support Software Operation
Manual (W369).
3. Transfer the project created on NS-Designer to the PT.
Starting and Stopping Data Links
The PT starts and stops data links according to the status of the data links when participating
in the network. If the data links are started when entering the network, the PT will start its
data links. If network has stopped data links, the PT will not start data links. The PT cannot
control starting/stopping data links independently. Control starting/stopping data links on the
Controller Link network using the startup node or CX-Server.
· The data link mode (manual setting or automatic setting) and data link method are deter-
Note
mined according to the data link setting in the startup node. In the startup node, set the
data link tables if manual settings are being used and data link automatic setting parame-
ters if automatic settings are being used. If the settings are incorrect, the data links will not
start.
· Check the following items before starting data links.
1. 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 par-
ticipating in the data links.
2. Automatically Set data Links
Be sure that the correct DM parameters have been set
in the data link startup node.
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 or parameters have been
set, do not start or stop data links before verifying that there
will be no adverse influence on the system.
