Remarks
Enables or disables the slave as a communications tar-
get.
• Enabled: The slave will operate.
• Disabled: The slave will not operate.
Set the following slaves as disabled slaves: slaves that
are not installed on the physical EtherCAT network but
are scheduled for addition at a later date or slaves that
not used due to changes in the device configuration
during system operation.
Even for disabled slaves, process data allocations can be
set and used as system-defined variables and device
variables in the user program.
Default setting: Enabled
Displays the serial number of the slave.
Default: 0x00000000 (when offline)
The value is updated to the serial number of the physical
slave when you select Get Slave Serial Numbers from
the menu for the master.
A Network Configuration Verification Error occurs if the
serial number on the Sysmac Studio and the serial num-
ber of the physical slave do not agree when the Serial
Number Check Method in the master settings is set to
Setting = Actual device.
Refer to 5-5-3 Using the Sysmac Studio to Obtain Serial
Numbers from the Actual Network Configuration for how
to access the serial number of the physical slave.
Default allocations of process data for slaves are provided
by the Sysmac Studio.
When the network configuration is created, device vari-
ables are automatically created in the initial process data
allocations. You can read and write these process data
allocations as device variables from the user program.
When valid PDOs are present, a list of them is displayed.
When valid PDOs are not present, "---" is displayed.
If editing the process data allocations is required, click the
Edit PDO Map Settings Button at the bottom of the list.
Refer to Changing the PDO Map Settings for details.
If a slave provides a distributed clock, Enabled is dis-
played.
If a slave provides a distribute clock which allows disable
setting, either Enabled or Disabled is displayed. You can
select enabling or disabling the clock.
If the distributed clock is enabled, you can select the syn-
chronization timing (Sync0 or Sync1) for some slaves. If
Sync0 is selected, Enabled (DC Sync0) is displayed.
If a slave does not provide a distributed clock, "---" is dis-
played.
