4.1 Operation
The Gateway
}
operates as a protocol converter between Modbus/TCP and EtherCAT,
}
operates on the Modbus/TCP side as connection Server and on the EtherCAT­side as
Slave,
}
Uses an LED to indicate whether there is data traffic via the connection
}
Uses an LED to indicate the interface used for this data traffic
}
If the connection to EtherCAT or to Modbus/TCP is no longer available, the payload is
retained with the current values
}
is exclusively designed for exchanging non­safety­related data
The Gateway is interposed in the data flow between the connected devices.
