Information about the target node that acts as the originator is displayed. If all tag data link connec-
tions to the node are established and normal, this information is displayed in blue. However, if any
connection is broken it is displayed in red. However, this information is displayed in gray if the con-
nection to the node is stopped. In addition, the Connection Status Area shows the current status of
each connection that is set as the originator. This information can be used to identify the cause of
tag data link errors. Refer to 15-3-2 Connection Status Codes and Troubleshooting for details on the
