3-4-1 Procedure to Assign Variables to Units
3-4 Allocating Variables to Units
For some instructions, the Units on EtherCAT Slave Terminals are specified by using variables. There-
fore, you must assign variables to the Units in advance. After you assign variables to the Units, the con-
nection locations of the Units are automatically updated in the variables even if you change the
locations. This means that you do not have to assign variables again every time you change the Unit
connection locations.
A CPU Unit with unit version 1.05 or later and Sysmac Studio version 1.06 or higher are required
to assign variables to Units.
You can assign variables to EtherCAT slaves other than Slave Terminals. This applies to Ether-
CAT slaves from other manufacturers. The variables are assigned to the EtherCAT slaves in the
same way as they are assigned to EtherCAT Coupler Units and NX Units.
The variables assigned to the Units are not created automatically when you make configuration settings
for an EtherCAT Slave Terminal on the Sysmac Studio. You must make the following settings to assign
the variables to the Units.
1
On the Sysmac Studio, select Configurations and Setup EtherCAT and make configuration
settings for EtherCAT Slave Terminals.
2
Select Configurations and Setup I/O Map to display the I/O Map.
The I/O Map is displayed for the Units of the set EtherCAT Slave Terminals.
3
Right-click the model of Unit to which you want to assign variables and select Display Node
Location Port from the menu.
The Node location information port will be added on the I/O Map.
4
Right-click the Node location information and select Create Device Variable.
The variable name will be written automatically to the Variable Field of the Node location
information port.
