3 Assigning Device Variables for CJ-series Units

3-2 Device Variables for the CJ-series
Unit
The section describes the device variables for the CJ-series Unit individually.
In this section, the variable names that are created automatically in the I/O Map are used.

Assigning Device Variables for CJ-series Units

An NJ-series Controller predefines the following three types of data as I/O ports for the operating data
and setup data of an EtherNet/IP Unit.
The device variables for the CJ-series Unit are assigned to I/O ports to use them.
(1) Software switches (Serve as commands from the CPU Unit to the EtherNet/IP Unit.)
(2) Status (Gives the status of the EtherNet/IP Unit, error information, network status,
and tag data link target status.)
(3) Setup (Stores the IP address that is set for the EtherNet/IP Unit.)
The three types of device variables for the EtherNet/IP Unit are described individually below.
Refer to A-6-2 Differences in Access Methods from the User Program for the operating data and setup
data addresses that correspond to the device variables for the CJ-series Unit.

Device Variables for the CJ-series Unit for Software Switches

These variables are used for outputs from the CPU Unit to the EtherNet/IP Unit.
Device variable name for
CJ-series Unit
*_TDLStartCmd
*_TDLStopCmd
*_AdjTmCmd
 Tag Data Link Start Bit (*_TDLStartCmd)
Start the tag data links by changing this variable to TRUE. If the tag data links are already operating,
the signal is ignored. The tag data links start operating automatically after the tag data link parame-
ter settings are downloaded from the Network Configurator, the power to the Controller is turned
ON, or the Unit is restarted.
If the Tag Data Link Stop Bit was changed to TRUE to stop the tag data links, you can restart the tag
data links by changing the Tag Data Link Start Bit to TRUE.
After the tag data links start, the EtherNet/IP Unit automatically changes the Tag Data Link Start Bit
to FALSE. Do not force this variable to FALSE. It is automatically changed to FALSE by the Unit.
