Information
If the value is greater than the configured bus cycle time, the cycle time
must be adapted correspondingly.
15.3.2.3 Consequence
An increment of these times has the following consequences:
● Reduction of the amount of data which can be transmitted on the bus,
because the time available for transmission is reduced.
● Reduction of the time between "reading inputs" and "writing outputs" at a
configured "fast control".
● Possibly necessary higher bus cycle time.
15.3.3 Configuring EtherCAT Slave
A new EtherCAT slave is attached to the existing EtherCAT Master node.
To do so, proceed as follows:
1) In the project tree at the node of the EtherCAT Master open the context
menu of a port (DRV0 or OUT0) and select Add Device.
2) In the open dialogue "Add Device" select an EtherCAT slave device and
click on Add Device.
3) Double-click on the newly inserted EtherCAT slave device in the project
tree.
An EtherCAT slave device has been inserted and the configuration window
opens. Depending on the insterted device, the configuration possibilities in
this window differ.
The configuration window for EtherCAT slave devices consists of the follow-
ing tabs:
● Basic Configuration: This tab displays the name of the device type and
allows the configuration of the basic settings.
● I/O Mapping: IEC variables can be mapped to endpoints. See also "Map-
ping Endpoints".
● FMMU/Sync: Under this, the settings for "Fieldbus Memory Management
Unit" and "Sync Manager" can be carried out.
● Start Parameters: Start parameters are set with the slave for each boot.
● Status: Shows information about the status of the slave device.
The following tabs are only visible when the expert settings have been acti-
vated:
● Expert Mode Process Data: Expert settings for the cyclical process data.
