Setting EtherCAT Slave Variables and
Axes
Device variables are used to read and write process data for EtherCAT slaves. Axis variables are used
to manipulate slaves to which axes are assigned from the Motion Control Function Module. This sec-
tion describes how to register device variables and set the axes.
5-3-1
Registering Device Variables for All EtherCAT Slaves
You use the I/O Map in the Sysmac Studio to assign device variables to the I/O ports. The device vari-
ables that you create are registered in the global variable table.
Use one of the following three methods.
• Selecting variables that were previously registered in a variable table
• Inputting new device variable names.
• Automatically creating device variable names
Selecting Variables That Were Previously Registered in a Variable
Table
You can select variables that are already registered on the menu on the I/O Map Tab Page.
For example, this method can be used to register device variables in the following cases.
• To write the program before the slave configuration information is created.
• To reuse programs from another project.
Use the following procedure.
1
Register the variables in advance in the global variable table or the local variable table of one
of the POUs.
2
Program using those variables.
3
Create the slave configuration information.
