Multi-protocol functionality
D301271 1013 - FGEN - multi protocol2-2
2.1 General
The compact I/O-stations of the product line FGEN combine the three Ethernet protocols EtherNet/IP™,
Modbus TCP and PROFINET in one device.
A multi-protocol device can be operated without intervention of the user (which means, without
changes in the parameterization) in all of the three Ethernet protocols mentioned.
During the start-up after a power-on, the module runs in "snooping" mode and detects the Ethernet
protocol which requests a link connection by listening the traffic.
If a protocol is detected, the device automatically changes to the detected protocol and ignores the
telegrams of the other two.
