6.2.2 Checking the serial number
This function extension is available from »Engineer« HighLevel V2.9 upwards!
The »Engineer« checks the serial number of the device when going online.
• The serial number is visible in the Properties tab.
• If a device accesses a communication path which is already in use, an error message will be
issued.
• The following situations may occur when establishing a connection:
• Communication path is currently being used by another device ( 94)
• Communication path is currently being used by another device ( 95)
6.2.2.1 Communication path is currently being used by another device
By means of the serial number the »Engineer« can spot a device that is connected online being
replaced by another device. Every time an online connection is established the »Engineer« compares
the serial number of the physical device with the serial number saved for this device. If the
communication path is currently being used by another device, a note will give information on the
use of the communication path.
Physical device replaced Physical device replaced Physical device and communication
path replaced
Example 1: "Replug" device on
diagnostic adapter
Example 2: Device exchange for
service purposes
Example 3: Device exchange and
different communication path
• The physical device A has been
projected as the device in the
»Engineer«.
• The physical device A is
"replugged" and replaced by the
physical device B.
• After confirming the query dialog
the present connection can be
used with the physical device B.
• The physical device A has been
projected as the device in the
»Engineer«.
• The physical device A (out of
order) is replaced by device A
(new).
• If servicing is required, device A
(new) can go online using the
present connection.
• The two devices A and B have
been projected and
commissioned in the »Engineer«.
• Ethernet, for instance, is the
communication path.
• The physical device A (out of
order) is replaced.
• Device A (new) goes online using a
new communication path, e.g.
diagnostic adapters.
• Device 2 goes online using
another communication path.
Device B remains unchanged.
