6 Operation as a PROFINET device
The switch is supported as a PROFINET device in PC Worx Version 5.00.26 or later. The
PROFINET IO controller is then responsible for starting up the switch within a PROFINET
application. This includes assigning the IP parameters, comparing the desired/actual con-
figuration, and archiving alarms sent by the switch. In the event that a device is replaced,
the controller recognizes the replacement device and starts it up automatically. For the con-
troller program, the switch as a PROFINET IO device will make available the link states as
a process data item.
6.1 Preparing the switch for PROFINET mode
By default upon delivery, the switch works in “PROFINET” operating mode.
The switch is delivered configured with the following default settings:
– The Link Layer Discovery Protocol (LLDP) is activated with the following configuration
specifications for PROFINET components:
- Message transmit interval: 5 s
- Message transmit hold multiplier: 2
- TLV port ID with subtype locally assigned in the following format: port-xyz
- TLV chassis ID with subtype locally assigned transmits the station name
– The Discovery and Configuration Protocol (DCP) is activated as the mechanism for as-
signing IP parameters.
– A station name (system name) has not been entered.
– The MRP protocol is not activated.
The switch starts in PROFINET operating mode for the first time and waits for a name and
a PROFINET IP address to be assigned. At this point the switch is already visible in the net-
work via the LLDP.
The switch cannot be accessed via other network services such as ping at this time.
6.2 Switch as a PROFINET IO device
6.2.1 Configuration in the engineering tool
6.2.1.1 Specifying the bus configuration
You can operate the switch as a PROFINET IO device if you integrate it under a
controller in the bus configuration in the engineering tool. A GSD and FDCML file
is available for the integration at
