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.
Note
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.
Note!
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.
To check the network address of the LES, switch to the Settings menu from detection
mode of the LES with the touch of a button.
In the
Ethernet
submenu (see Chapter 7.2.1), you can read the current settings of the LES
one after the next by pressing
.
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.
Instead of
xxx
you can now allocate any numbers between 000 and 255 to your PC, but
NOT THE SAME numbers as contained in the address of the LES.
