Starting And Stopping Tag Data Links; Controller Status - Omron NY532-5400 User Manual

Additional Information
• To calculate the number of connections of each connection type, refer to 13-1-2 Calculating
the Number of Connections.
• If the maximum number of connections is exceeded, you must review the number of connec-
tions for the built-in EtherNet/IP port, or the number of nodes. When you use an NJ-series
CPU Unit, you can also consider adding EtherNet/IP Units.

Starting and Stopping Tag Data Links

Tag data links are automatically started when the data link parameters are downloaded from the Net-
work Configurator and the power supply to the NY-series Controller is turned ON. Thereafter, you can
start and stop tag data links for the entire network or individual devices from the Network Configurator.
Starting and stopping tag data links for individual devices must be performed for the originator. Further-
more, you can use system-defined variables to start and stop the entire network. Refer to 7-2-12 Start-
ing and Stopping Tag Data Links for details.

Controller Status

You can include the Controller status as a member of a tag set in the data sent and received. The Con-
troller status is a set of flags that indicate the operating status of the Controller (operating information,
error information, Controller error level). If the Controller status is specified as an output (send) tag, the
Controller status is added to the start of the tag set in the following format. (Select the Include Option
for the Controller Status in the upper right of the Edit Tag Set Dialog Box.)

* Of the flags in bits 5 to 7 that indicate the current error level, only the flag for the highest error level changes to
TRUE. For example, if a minor fault level Controller error and a major fault level Controller error occur at the
same time, only the flag for the major fault level Controller error (bit 7) will change to TRUE and the flag for the
minor fault level Controller error (bit 5) will remain FALSE.
To receive the Controller status, specify the Controller status for the In - Consume Tab Page in the dia-
log box used to edit the receive tag set. (Select the Include Option for the Controller Status in the upper
right of the Edit Tag Set Dialog Box.) When a tag data link is started, the contents of the Controller sta-
tus is stored in the system variables that are given below.
