EtherCAT provides the following two types of communication functions.
This is cyclic (I/O) communication.
The EtherCAT Master Unit maps logical process data space (cyclic data space) to each slave node,
and realizes cyclic (I/O) communications with Slave Units.
This is message communication.
The EtherCAT Master Unit transmits commands to Slave Units, and the sSave Units return responses
to the EtherCAT Master Unit.
The data below is sent and received.
•
Read and write process data
•
Slave settings
•
Monitor slave state
