Fig.

“Basic EtherCAT Slave Diagnosis in the PLC”

shows an example of an implementation of basic

EtherCAT Slave Diagnosis. A Beckhoff EL3102 (2-channel analogue input terminal) is used here, as it offers
both the communication diagnosis typical of a slave and the functional diagnosis that is specific to a channel.
Structures are created as input variables in the PLC, each corresponding to the process image.
