Include the devices identified online manually in the project
Requirements
You have run an offline/online comparison in the topology view. The result of this is that at
least one device identified online could not be assigned to any configured device.
To adopt one more devices identified online in the project manually, follow these steps:
1. For a configured device without an online partner, move the mouse pointer to the
"Device/port" column of the online topology.
2. Select the device you want to assign to the configured device from the drop-down list of
this box.
3. Repeat the previous steps if necessary for other configured devices without an online
partner.
The selected device that was identified online is moved up from the end of the table.
Following this, it is in the row of the configured device to which you have just assigned it.
Automatic assignment of devices by advanced offline/online comparison
Overview
With the advanced offline/online comparison, ICMP is also used alongside DCP to be able to
detect devices that do not support DCP.
Automatic assignment of devices detected by ICMP
With devices detected by ICMP, no type is available.
With passive devices, no article number is available. For this reason, passive devices can
only be assigned automatically if you have not assigned an article number in the configured
data and the offline and online IP addresses match.
With switches, automatic assignment is possible if the offline and online article number, IP
address and PROFINET device name match.
