Sample configuration with EP1122 2-port EtherCAT junction
The counting direction is to be observed when using an EP1122; it is comparable with the EK1122. If
EtherCAT junction 1 on the EP1122 is connected, then the EtherCAT frame is forwarded here first (1); if
junction 1 is not connected the frame on junction 2 is sent (2), only after that does the sequence continue
with the EC-bus on the right-hand side (3).
Fig. 29: Sample configuration with EP1122 2-port EtherCAT junction
If both junctions are not used, then junction 1 and 2 are short-circuited as it were and the EC frame
continues directly from the terminal to the right.
Note that in the Profinet controller the modules are entered in the direction of the EtherCAT frame.
Connection during operation
You cannot use the EP1122 and EK1122 for Hot Swap or connect or disconnect them during opera-
tion. The EP1122 and EK1122 are suitable in conjunction with the EK coupler only as topology ex-
tensions (star).
