Configuration of the EtherCAT® Master

Double-click on CM579_Master (CM579-Master) to open the Master configuration dialog in the editor window:

The following parameters are available:

Parameter	Default	Value	Meaning	Parameter (Remark 1 Configuration of the EtherCAT® Master)
Autoconfig Master/Slaves Remark 2 Configuration of the EtherCAT® Master:	Enabled	Disabled	The automatic configuration is disabled.	Autoconfig
		Enabled	The configuration parameters are set automatically based on the given device description and network topology. Normally the parameters do not have to be modified for standard applications.
Ethercat NIC Setting
Destination Address (MAC)	FF-FF-FF-FF-FF-FF	Valid MAC address	Parameter Destination Address (MAC) determines the MAC address of the participant of the EtherCAT® network which should receive the telegrams. If option Broadcast is activated, no specific address must be entered.	DestAddress1 and DestAddress 2
Source Address (MAC)	00-00-00-00-00-00	Valid MAC address	Parameter Source Address (MAC) determines the MAC address of the system.	SrcAddress1 and SrcAddress2
Network Name	empty	String	Parameter Network Name determines the network name of the system.	NetworkName
		Select network by MAC	If this option is selected, the network is selected by the MAC address determined by parameter Source Address (MAC).	SelectNetworkByName = FALSE
		Select network by Name	If this option is selected, the network is selected by the network name determined by parameter Network Name.	SelectNetworkByName = TRUE
Broadcast	Enabled	Disabled	The destination address is not the broadcast address. The parameter Destination Address (MAC) must be edited.	-
		Enabled	The destination address is set to broadcast address FF-FF-FF-FF-FF-FF. The parameter Destination Address (MAC) can not be edited.
Distributed Clock
Cycle time	4000	0…10000	Period of time in [µs] after which a new data telegram is to be sent on the bus. If the Distributed Clock functionality is activated, the master cycle time will be transferred to the slave clocks. Thus an accurate synchronization of data exchange can be reached, which is particularly important in cases where spatially distributed processes require simultaneous actions (e.g. in applications where several servo axes carry out coordinated movements simultaneously). So a very precise network-wide timebase with a jitter of significantly less then 1 microsecond can be achieved.	MasterCycleTime
Options
Use LRW instead of LWR/LRD	Disabled	Disabled	Slave-to-slave communication is not allowed.	MasterUseLRW
		Enabled	Slave-to-slave communication is allowed.
Enable messages per task	Disabled	Disabled	This parameter is currently not supported.	EnableTaskMessage
		Enabled
Auto restart slaves	Disabled	Disabled	This parameter is currently not supported.
		Enabled
Master Setting (only available if AutoconfigMaster/Slaves option is disabled)
Image In Address	16#10880	16#00000000… 16#FFFFFFFF	Parameter Image In Address determines the first logical address of the first slave for input data.	ImageInAddress and ImageInLength
Image Out Address	16#10000	16#00000000… 16#FFFFFFFF	Parameter Image Out Address determines the first logical address of the first slave for output data.	ImageOutAddress and ImageOutLength

Remark 1: Tab CM579-Master Configuration

The parameters in this column are shown in tab EtherCAT® Configuration which is only visible if the parameter Show generic device configuration views is activated (open the Options dialog window with menu item Tools -> Options, parameter is located under section Device editor):

The table shows all configuration parameters.

Remark 2: Autoconfig

The autoconfig mode is activated by default and usually sufficient and strongly recommended for standard applications. If the option is deactivated, all configuration settings for the Master and the Slave(s) will have to be done manually and expert knowledge is required. For the configuration of a slave-to-slave communication the autoconfig option has to be deactivated.
