Pressing the Search Device button will let the PC search the connected
Ethernet networks for PROFINET IO devices. Therefore the PC must have an
Ethernet connection to the PROFINET network.
All PROFINET IO Controllers and IO Devices found will be shown with their:
• MAC Address, which is fixed by the in the device and makes it unique pm
the Ethernet network.
• Device Type, is fixed by the Vendor and is often just the product name
• Device Name, is set by the user and is fixed in the device. This name is
used by the IO Controller to find the IO Device before setting up
connections.
• IP Address the device currently holds. It could be temporary or fixed but
For an IO Device it will be over written by a value set in the configuration of
the IO Controller.
• Protocol that is used to find the device.
The Configure button will display four other selections that can be performed
on the selected PROFINET IO Controller or Device:
• Signal will let the LEDs of the selected device flash for 3 seconds. This is
useful to physically find the device in the installation. When found the
device can get a logical name.
• Set IP Address... will set the IP Address of the selected device. The IP
Address can be fixed or temporary. But finally the IO Controller will over
write the IP address when it esthablishes a connection to the IO Device.
However a temporary IP-Address can come in handy when up- or
downloading SmartSlice configurations with the GRT1-PNT PROFINET IO
Device DTM when no IO Controller is available.
• Set Device Name... needs to be done because a IO Device needs to have
a name. This is the only way a IO Controller can find an IO Device on the
network. This same Device Name must be entered in the IO Controllers
configuration.
• Reset to factory defaults... as the title suggests will reset the device to its
factory defaults like default name and IP-address 0.0.0.0.
