7-2-12 Starting and Stopping Tag Data Links
• Change the Tag Data Link Start Switch to TRUE, while the Tag Data Link Communications
Stop Switch is FALSE. If the Tag Data Link Stop Switch is TRUE, the tag data links do not start
even if the Tag Data Link Start Switch is changed to TRUE. Furthermore, if the Tag Data Link
Start Switch and the Tag Data Link Stop Switch are both TRUE, an error occurs, the Multiple
Switches TRUE Error system-defined variable changes to TRUE, and the event is recorded in
the event log.
• After you start the tag data links, do not force the Tag Data Link Start Switch to change to
FALSE from the user program or from the Sysmac Studio. It will change to FALSE automati-
cally.
