The E-bus signals and the supply voltage of the field side UP are routed

directly to the signal distribution board via a plug connector at the rear of

the EtherCAT EJ Coupler. Thanks to the direct coupling of the Embedded

PC and EtherCAT terminals with the EtherCAT plug-in modules on the PCB,

no EtherCAT extension (EK1110) or EtherCAT Coupler (EJ1100) is required.

The system and field supply of the EK1110-0044 is provided by the power

supply unit of the Embedded PC. In addition, the EK1110-0044 has an RJ45

socket that enables connection of an Ethernet cable with RJ45 connector

and establishes a connection to a further EtherCAT segment or to individual

EtherCAT devices.

The Embedded PC can be extended with EtherCAT Terminals that are not

yet available in the EJ system, for example. The preassembled subsystem, 

consisting of a printed circuit board with mounted DIN rail, Embedded PC

and EtherCAT plug-in modules, can be tested in advance and subsequently

integrated into the machine assembly as a complete unit.
