EtherCAT NIC Setting
Destination Address (MAC): 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.
Source Address (MAC): resp. Network Name: MAC address resp. name of the card, i.e.
PLC (target system)
For this choose one of the following options
Select network by MAC
Select network by Name
Before setting one of the options consider the following: Each network adapter has an
unique MAC-ID. So, if you now specify the network by MAC-ID, you will not be able to
use this project also on another device. If you want to get your project independent
from the device, better specify the network by its name.
In both cases the Browse button can be used to get the currently available target
devices' MAC-IDs resp. names.
Distributed Clock
Master Cycle [µs]: Period of time 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 (for example 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.
Diagnostics Message: In online mode the startup run will be watched and the
respective diagnostic messages will be displayed. If message "All slaves done" appears,
the configuration is finished and the bus is running.
Options
Use LRW instead of LWR/LRD : Activation of this option enables slave-to-slave
communication. Instead of a separate read (LRD) and write commands (LWR),
combined read/write commands (LRW) will be used.
Enable messages per task : If this option is activated, read and write commands, that is
handling input and output messages can be done with different tasks.
Auto restart slaves: If this option is activated, the master always will try to restart the
slaves as soon as the communication aborts.
