1.3.1.1.6 Diagnosis
The AC500 processor module can display various errors according to the error classes. The
following error classes are possible. The reaction of the processor module is different for each
type of error.
Error class
E1
ERR-LED is ON
E2
ERR-LED is ON
E3
ERR-LED is ON/OFF
*)
E4
ERR-LED is ON/OFF
*)
*) The behaviour if the ERR-LED lights up at error classes E3 or E4 is configurable.
Occurred errors can be displayed with the commands diagshow all in the PLC-Browser of
Automation Builder software.
1.3.1.1.7 Onboard I/Os
The AC500-eCo V3 processor modules have onboard I/Os which provide several functionalities.
According to the CPU type, the number or the functionality of the onboard I/Os can be different.

Description
A safe function of the operating
system is no longer guaranteed.
The operating system is func-
tioning without problems, but the
error-free processing of the user
program is no longer guaranteed.
It depends on the application
if the user program should be
stopped by the operating system
or not. The user should deter-
mine which reaction is necessary.
Error in the periphery (e.g. I/O)
which may show an impact in
the future. The user should deter-
mine which reaction is necessary.
