Indicators on controllers

All IndraControl S20 modules are provided with diagnostics and status indicators
for quick local error diagnostics. They enable the clear localization of system errors
(bus errors) or I/O errors.
The diagnostics indicators (red, yellow or green) provide information about the
state of the module and, in the event of an error, provide information about the type
and location of the error. The module is functioning correctly if all of the green
LEDs are on.
The status indicators (yellow) display the status of the relevant input/output and
the connected I/O device.
Some modules have extended diagnostics. A short-circuit or an overload of the
sensor supply, for example, can be detected and reported. If a short circuit occurs
at an output, some output modules can diagnose each channel individually. Infor-
mation about the supply voltage is also reported. Information about I/O errors is
sent to the controller with precise details of the error type and is displayed using
status indicators.
The diagnostics indicators D, UA, E1, E2 show the current status. This
status is not saved. This means, for example, that an open circuit or
overrange is indicated via the LEDs. If the respective error has been
removed and no other error has occurred, the LEDs indicate the error-
free state again.
The error is not saved on the module.
For some modules, however, the DiagState object (0018
report some specific errors to the controller.
Please refer to the module-specific documentation for information re-
garding the diagnostics and status indicators on each module and
their meaning.
All possible positions for diagnostics and status indicators are
equipped with light guides on the S20 connectors.
Since not every position has its own LED on the printed-circuit board,
there are some light guides without any function.
Examples:
A20-AI-8: The light guides 00 ... 07, 10 ... 17, 20 ... 27, and 30 ... 37 do
not have any function.
S20-DI-32/1: The light guides 00 ... 07, 10 ... 17, 20 ... 27, and 30 ... 37
have a function.
Please refer to the module-specific documentation for information re-
garding the diagnostics and status indicators on each module and
their meaning.

of the controller, please refer to the corresponding documentation:
