4.4.2.2 EtherCAT bus in operation (gateway function)
You communicate directly via EtherCAT and use the controller as a gateway.
[4-6] Example: EtherCAT bus system with 3231 C controller as gateway and i700 servo inverter
Condition:
• The EtherCAT configuration has been created with »PLC Designer« to match the hardware
configuration.
• The EtherCAT configuration has been loaded and activated on the controller with »PLC
Designer«.
• The EtherCAT bus is at least in the "Pre-Operational" state.
Advantage:
• You do not require any additional hardware.
• The process data, parameter data and diagnostic data are transferred via a single bus
connection at the same time.

Note!
A PLC program does not need to run to be able to use the gateway function.
