Diagnostic and status indicators
All Inline Block IO modules and Inline Modular IO terminals (referred to below as the device)
are equipped with diagnostic and status indicators for quick local error diagnostics. They
enable the clear localization of system errors (bus errors) or peripheral faults.
The diagnostic indicators (red, yellow or green) provide information about the state of the
device and, in the event of an error, provide information about the type and location of the
error. The device is operating correctly if all of its green LEDs are on.
The status indicators (yellow) indicate the status of the relevant input/output and the
connected I/O device.
Some devices have extended diagnostics. A short circuit or overload of the sensor supply
is indicated for each input. If a short circuit occurs at an output, each channel is diagnosed
individually. Information about the supply voltage is also reported. Information about
peripheral faults is sent to the control system with precise details of the error type and is
displayed using status indicators.
