Registering Device Variables and Attributes
 Registering Device Variables
You assign device variables to I/O ports in the I/O Map of the Sysmac Studio. The device variables
that you create are registered in the variable table.
 Device Variable Attributes
This section describes the attributes for the device variables that are used with the EtherCAT Slave Ter-
minal.

NX-series EtherCAT Coupler Unit User's Manual (W519)
Specification method
There are three ways to assign a device variable.
• Select a registered variable from the variable table.
• Manually enter the device variable name.
• Automatically create the device variable name.
Variable names are automatically created using the fol-
lowing convention:
device_name+I/O_port_name
Specify the data type of the I/O port. You must also spec-
ify a data type of the same size as the data type of the I/O
port.
ECAT://node#[node_address.NX_Unit_number]/I/O_port
_name
Examples:
For an EtherCAT Coupler Unit whose node address is 10,
and a Digital Input Unit (NX-ID3317 Four-point Input Unit)
whose NX Unit number is 15:
ECAT://node#[10,15]/Input Bit 00 to
ECAT://node#[10,15]/Input Bit 03
