Overview of Tag Data Links
Make the following settings using the Network Configurator if tag data link
functionality is used with the CJ2B-EIP21 built-in EtherNet/IP port on the
CJ2H, CJ2M-EIP21 built-in EtherNet/IP port on the CJ2M, CS1W-EIP21, or
CJ1W-EIP21.
Create input (reception) tags and output (send) tags for addresses in the CPU
Unit's I/O memory areas or for symbols.
The following are the limits for tags that can be created with the CJ2B-EIP21
built-in EtherNet/IP port on the CJ2H, CJ2M-EIP21 built-in EtherNet/IP port
on the CJ2M, CS1W-EIP21, or CJ1W-EIP21.
With the CJ2H-CPU6@-EIP or CJ2M-CPU3@, you can create tags by import-
ing network symbols (i.e., I/O allocation settings) that were created using the
CX-Programmer into the Network Configurator. Output tags can be defined to
clear output data to 0 or to hold the output data when PLC outputs are turned
OFF.
Create output tag sets and input tag sets and position them. (Up to eight tag
sets can be created). The following are the limits on tag sets that can be cre-
ated with the CJ2B-EIP21 built-in EtherNet/IP port on the CJ2H, CJ2M-EIP21
built-in EtherNet/IP port on the CJ2M, CS1W-EIP21, or CJ1W-EIP21.
The PLC status can be specified in a tag set to indicate the CPU Unit’s operat-
ing status (operating information and error information).
The target device output tag set and the originator device input tag set are
associated as connections. A maximum of 256 connections can be opened
per Unit for the CJ2B-EIP21 built-in EtherNet/IP port on the CJ2H, CS1W-
EIP21, or CJ1W-EIP21. A maximum of 32 connections can be opened per
Unit for the CJ2M-EIP21 built-in EtherNet/IP port on the CJ2M.
The number of connections is the total of the number of input tag sets that
receive data and the number of nodes that send data for output tag sets.
(Refer to the following figure.) One connection is consumed for each connec-
tion setting whether the connection is a multicast connection or a unicast
(point-to-point) connection.
