Precautions
Tag communications cannot be executed depending on the connection setting details.
The following figures show the tag conditions that cannot be set to the CC-Link IE TSN Plus module or under which tag
communications cannot be executed.
• A Producer Tag with the same tag name cannot be set to the CC-Link IE TSN Plus module regardless of its data size. (Tag
names are not case-sensitive.)
Consumer
• The setting for opening multiple connections for the Producer Tag held by the external device cannot be made. (Multiple
Consumer Tags with the same tag name cannot be set for one external device.) (Tag names are not case-sensitive.)
Consumer
External device: Producer1
Consumer Tag1
Tag name: Class1_Data1
Data Size: 8
External device: Producer1
Consumer Tag2 Tag name: Class1_Data1
Data Size: 8
However, for Producer Tags with the same tag names held by different external devices, a connection can be opened
individually.
In this case, since they are independent, the connection settings do not need to be the same. (Including data sizes)
Consumer
External device: Producer1
Consumer Tag1 Tag name: Class1_Data1
Data Size: 8
External device: Producer2
Consumer Tag2 Tag name: Class1_Data1
Data Size: 16
• When the data size of Producer Tag is different from the data size of Consumer Tag, Producer may send an error response
to Consumer.
