Functions and operating modes
4.3.1
Multiprotocol technology
The devices can be used in the following three Ethernet protocols:
n
Modbus TCP
n
EtherNet/IP
n
PROFINET
The required Ethernet protocol can be detected automatically or determined manually.
Automatic protocol detection
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 system start-up phase (snooping phase), the module detects which Ethernet pro-
tocol requests a connection to be established and adjusts itself to the corresponding protocol.
After this an access to the device from other protocols is read-only.
Manual protocol selection
The user can also define the protocol manually. In this case, the snooping phase is skipped and
the device is fixed to the selected protocol. With the other protocols, the device can only be ac-
cessed read-only.
Protocol dependent functions
The device Supported the following Ethernet protocol specific functions:
PROFINET
n
FSU - Fast Start-Up (prioritized startup)
n
Topology discovery
n
Address assignment via LLDP
n
MRP (Media Redundancy Protocol)
EtherNet/IP
n
QC – QuickConnect
n
Device Level Ring (DLR)
