8 Operating as a PROFINET Device
The switch is supported as a PROFINET device in PC WorX Version 5.00.26 or later. In a
PROFINET application, the PROFINET IO controller is responsible for starting up the
switch. This includes assigning the IP parameters, comparing the desired/actual
configuration, and archiving alarms sent by the switch. In the event that a device is
replaced, the control system detects the replacement device and starts it up automatically.
For the control program, the switch as a PROFINET IO device provides the link states as
a process data item.
8.1 Preparing the Switch for PROFINET Mode
By default upon delivery the switch operates in "Default" mode and must be set to
"PROFINET" mode once.
Switching to "PROFINET"
mode
Two mechanisms are available for switching the mode:
– Following startup and assignment of an IP address, the operating mode can be
changed on the corresponding page in WBM (see ""Operating Mode" Web Page"on
page 4-20)
– Through configuration via the serial interface (see "Management via Local V.24 (RS-
232) Communication Interface"on page 4-116)
When activating "PROFINET" mode, the following default settings are made for operation:
– The Link Layer Discovery Protocol (LLDP) is enabled 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
assigning IP parameters.
– The station name (system name) is deleted if the value for the "System Name" object
contains the device type (default upon delivery).
In addition, when switching to "PROFINET" mode, the configuration is saved automatically
and the device is restarted.
The switch then starts in "PROFINET" mode for the first time and waits for a PROFINET
IP address to be assigned. At this point, the switch is already visible in the network via
LLDP with the default name "FL SWITCH MM HS" and the IP address "0.0.0.0".
Waiting for a valid IP configuration via DCP is indicated by the switch with "dP" in the
display and by the flashing of the LED for the currently active mode.
The switch cannot be accessed via other network services such as ping at this time.
