Operation
The Gateway
} operates as a protocol converter between Modbus/TCP and CANopen,
} operates on the Modbus/TCP side as connection Server and on the CANopen-side 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 CANopen or to Modbus/TCP is no longer available, the payload is
retained with the current values
} is exclusively designed for exchanging non-safety-related data
The Gateway is interposed in the data flow between the connected devices.
Protocol conversion, Modbus/TCP to CANopen
