yellow
Input variables from the Slave to the EtherCAT Master, updated in every cycle
red
Output variables from the Slave to the EtherCAT Master, updated in every cycle
green
Information variables for the EtherCAT Master that are updated acyclically. This means that
it is possible that in any particular cycle they do not represent the latest possible status. It is
therefore useful to read such variables through ADS.
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.
