Commissioning and configuration
8.1
Switching on
After switching on the supply vU
B
and following error-free initialization of the device,
the green LED illuminates continuously: the LES is in measure mode.
Notice
After a warmup time of 30 min., the light section sensor has reached the operating temper-
ature required for an optimum measurement.
8.2
Establish connection to PC
The LES is configured via a PC using the LESsoft program before it is integrated into the
process control.
In order to be able to establish an UDP communication with the PC, the IP address of your
PC and the IP address of the LES must lie in the same address range. The LES has no built-
in DHCP client, so that you need to set the address manually. This is done the easiest way
via the PC.
Notice!
If you use a desktop firewall, please make certain that the PC can communicate with the
LES via the Ethernet interface by means of UDP on ports 9008 and 5634 (these ports
are preset at the factory, but may have been changed by the user, see chapter 7.2
"Menu description"). Furthermore, the firewall must allow ICMP echo messages to pass
through for the connection test (ping).
If the PC is usually connected to a network using DHCP address allocation, the easiest way
to access the LES is by applying an alternative configuration in the TCP/IP settings of the
PC and connecting the LES to the PC.
Check the network address of the LES by pressing the
button during measure mode
of the LES twice in succession, then by pressing
twice and followed by pressing the
button
again.
This will take you to the
Ethernet
submenu and enable you to read the current settings of
the LES consecutively when pressing
repeatedly.
Make a note of the values for
IP-Address
and
Net Mask Addr.
.
The value in
Net Mask Addr.
specifies which digits of the IP address of the PC and LES
must match so that they can communicate with each other.
