Operating as a PROFINET Device

The PROFINET variables can then be created and used in the control program.
In addition to the "PNIO_DATA_STATE" standard variables, the switch provides the link
status as a process data byte for each port. If the "PNIO_DATA_VALID" bit for the
"PNIO_DATA_STATE" variables declares the switch process data as valid, the process
data item for a port can have the following values:
Value = 1 - active link
Value = 2 - no active link
Value = 3 - link present, but partner cannot establish link (only for FX ports - Far End
Fault Detection)
Process data can only be accessed if the parameterized desired configuration on device
startup corresponds to the actual configuration.
The "Status" word and the "Control" word of the management agent are not used.
8.2.3 PROFINET Flashing Function
If the switch is requested to flash in PROFINET mode by the engineering tool, "00" and the
previous current indication alternately flash in the display.
8.2.4 Naming the Device
In order to start up a switch in "PROFINET" mode, each switch must be assigned a name
once, i.e., each PROFINET device is assigned a unique device name. A device search
("Read PROFINET" function in PC WorX) is performed via the engineering tool, where all
the devices that can be accessed in the network are listed. After identifying unknown
devices via the specified MAC address or the "flashing" function, the device name
configured in the engineering tool is saved permanently on the switch with the "Assign
Name" function.
8.2.5 Operating in the PROFINET Environment
A switch that has already been assigned a name starts in "PROFINET" mode without an
IP address and waits for the assignment of an IP configuration ("dP" in the display and
flashing of the LED for the currently active mode). Once the project has been translated
and downloaded to the control system, the control system implements startup and
configuration. As soon as a communication relationship has been successfully established
between the switch and the control system, the switch starts its management interface.
The switch indicates that the PROFINET connection has been established correctly by an
entry in the results table and the appearance of an additional dot in the bottom-right corner
of the display.
The device name can also be assigned via WBM before switching to "PROFINET" mode.
If the MMS has established a PROFINET connection, a dot appears in the bottom-right
corner of the display.
