Overview Of Operation - Omron NJ Series User Manual

specify the variable with the AT specification for the tag. For NX102 and NX1P2 CPU Units, you need to set
CJ memory to use the I/O memory address.
For details on CJ memory setting, refer to the NJ/NX-series CPU Unit Software User's Manual (Cat. No.
W501).
*2. You can import network variables created in the Sysmac Studio to the Network Configurator as tags.
If variables for which Network publish attribute is set on the Sysmac Studio contain I/O memory addresses,
such as "0000" and "H0000", they are not exported to CSV files.
*3. The following table lists variables that you can specify as tags.
Variables with basic data types
Enumerated variables
Array variables
Structure variables
Union variables
*4. The maximum number of tags is given for the following conditions.
•
All tag sets contain eight tags.
•
The maximum number of tag sets (32) is registered.
*5. If more than 40 tag sets are set in total, a Number of Tag Sets for Tag Data Links Exceeded (840E0000 hex)
event occurs.
*6. If the two built-in EtherNet/IP ports are used simultaneously, the maximum communications data size al-
lowed for two ports in total will be reached.
*7. An NX102 CPU Unit with unit version 1.31 or later is required to use the CIP Safety routing.

Overview of Operation

In this manual, the connection information that is set is called tag data link parameters.
This section describes how to set tag data links with the Sysmac Studio and the Network Configurator.
Setting Network Variables (Sysmac Studio)
First, create any variables that you want to use for tag data links as network variables on the Sysmac
Studio.
1
Set the Network Publish attribute to Input or Output in the Global Variable Table for variables
you want to use for tag data links (i.e., as tags).
2
To maintain concurrency in tag data within a tag set, set all tags (i.e., variables with a Network
Publish attribute) within the same tag set as follows:
Set a refreshing task for variables with a Network Publish attribute to maintain concurrency for
tag data link data as described below.
Refer to 7-1-7 Concurrency of Tag Data Link Data on page 7-12 for details on the concurren-
cy of tag data link data.
• Maintain concurrency in the tag data in a tag set.
• The timing of updating network variables that are assigned to tags is synchronized with the
execution period of a program that accesses the network variables.
