Available on the PWR M12 plug and on the SW IN/OUT M12 socket are four freely programmable
switching inputs/outputs that can be individually adapted to the respective application (see chapter 7.2,
Standalone operation in Ethernet network
During stand-alone operation of the device, the host interface of the superior system is connected to
HOST/BUS IN. Thus, a star structure (Ethernet structure) is possible. Please be certain to select the
correct protocol for the connected components.
Network operation in Ethernet network
In network operation, the superior system (PC/PLC) is connected to the host interface of the device. With
the aid of the switch integrated in the device, the bus connection to the next participant, e.g. another
device, can occur directly via the BUS OUT socket!

Connecting functional earth FE
Ensure that the functional earth (FE) is connected correctly. Unimpaired operation is only guaranteed
when the functional earth is connected properly. All electrical disturbances (EMC couplings) are dis
-
charged via the functional earth connection.
Switching input/output
The device is equipped with four freely programmable, opto-decoupled switching inputs and outputs
SWIO_1 … SWIO_4.
The switching inputs can be used to activate various internal functions of the device (decoding,
autoConfig, …). The switching outputs can be used to signal the state of the device and to implement
external functions independent of the superior control.
The two switching inputs/outputs SWIO_1 and SWIO_2 are located on the SW IN/OUT M12 socket (see
chapter 7.4). The other two (SWIO_3 and SWIO_4) of the four freely configurable switching inputs/outputs
are located on the PWR M12 plug.
The device does not have its own built-in DHCP server. Please make certain that each partici
-
pant in the Ethernet has its own unique IP address. This can be set by a DHCP server in the
superior system or through manual address assignment.
