ADVANCED CONFIGURATION MODE
SG Extended UI software (Graphic User Interface, GUI) for PC allows the user to set ESPE
advanced configuration. Many parameters are available to customize ESPE behaviour for
specific applications.
Since ESPE parameters can be safety critical and PC software cannot be guaranteed as a
safety component, a safe configuration procedure has to be followed.
Configuration procedure on UI can be done by authorized personnel only. Such personnel
must be sure that protected dangerous machine has no access during configuration
procedure.
There are 3 different kinds of operator that can use the GUI with 3 different levels of
authorizations.
System Integrator:
has all the possible authorizations and can set every configuration on
the GUI
Maintainer:
can upload the configurations (saved on the GUI) on the light curtain and use
the GUI for monitoring the system, but he can’t create new configurations
Machine Operator:
uses the GUI only for monitoring the system
Depending on the kind of operator there are different passwords that protect some functions
of the GUI.

1) Device selection:
user selects ESPE to configure, choosing among devices on
network identified by a unique Serial Number
2) Parameters selection:
user sets required ESPE configuration.
After selection user sends configuration command, ESPE switches to SAFE state, a
“configuration in progress” indication is shown on ESPE led interface, old
configuration on ESPE is erased
3) Report check:
ESPE sends back to UI the received configuration, UI produces a
printable SAFETY REPORT with all safety related informations about configuration in
progress (Fig. 29). After checking all report contents user can accept configuration:
ESPE restarts in normal operation with the new configuration
4) ESPE Check:
user checks if ESPE is working according to SAFETY REPORT
(resolution check with proper test piece, parameters check …)
