NOTE
To protect the communication cable from any tension and to ensure
communication stability, fix the cable end which is near the device
before EtherCAT communication.
Configuration and use
1) When using this branch device, run all EtherCAT slaves (including the two
stations of this branch device) with an alias, so that an abnormal branch will
not affect the others.
2) The data flow priority of a 6-way branch device interface is X2>X3>X4>X5>X6, that is,
any slave on the X2 branch has priority over all slaves on the X3 branch.
3) The DC mode is enabled by default. That is, the branch device has been configured
as an EtherCAT slave in DC mode.
4)
The branch device allows cascade, and the allowable number of nodes is not
restricted by the device.
5)
Each branch device occupies two EtherCAT slave station numbers.
