In the Sysmac Studio project, an EtherCAT slave configuration is created for all seven EtherCAT slaves
and axes in A to G in the figure.
On the Sysmac Studio, set the EtherCAT slave enable/disable settings, Axis Use parameter settings,
and the associated program run/stop status at the start of operation for nodes A to G as shown in the
following table. These are the settings for the configuration before change.
The following procedure is used to change the EtherCAT slaves and axes that are used from C, D, E to
F and G.
1
Stop production line 4.
2
Use the MC_ChangeAxisUse instruction to set the Axis Use parameters for C, D, and E to
Unused Axis.
3
Use the EC_ChangeEnableSetting instruction to disable the settings for EtherCAT slaves C, D,
and E.
4
Use the PrgStop instruction to disable the programs associated with C, D and E.
5
Remove EtherCAT slaves C, D, and E from production line 4.
6
Install EtherCAT slaves F and G on production line 4.
7
Use the EC_ChangeEnableSetting instruction to enable the settings for EtherCAT slaves F and
G.
8
Use the MC_ChangeAxisUse instruction to set the Axis Use parameters for F and G to Used
Axis.
9
Use the PrgStart instruction to enable the programs associated with F and G.
10
Start production line 4 again.
As the result of the above steps, the EtherCAT slave enable/disable settings, Axis Use parameter set-
tings, and the associated programs enable/disable settings are changed as shown below.
When you want to disable the program, first disable the EtherCAT slave and axis which the pro-
gram is associated with, and then disable the program.
