Interface description
EtherCAT process data
The bus coupler and the ctrlX CORE are provided with 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. This information can also be retrieved via acyclic services using CoE. These are shown as
the indices 6000, 6010 and 6020 hex.
