Interface description
Process data of the bus coupler
The bus coupler has data that is inserted into the cyclic process image. This data length is 5 words
in total. According to the Ethercat standard, this data before the input process data is shown in the
process image.
The process data words 0...3 contain the voltage and current values of U
consumption of the infeed terminal and the I/O modules) as well as their bits for the supply voltage
diagnostics of the bus coupler. This information can also be retrieved via acyclic services using CoE.
These are shown as the indices 6000, 6010 and 6020 hex.

(Only the current consumption of the infeed terminal (typ. 50 mA) and the
I/O modules (3 A max.) is measured. In addition to the transferred measured
value (typ. 350 mA), the ctrlX CORE and the multi-Ethernet unit consume
more than shown here.
