9 Diagnostic and status indicators

All Inline Block IO modules and Inline terminals (referred to below as the device) are

equipped with diagnostic and status indicators for quick local error diagnostics. They en-

able the clear localization of system errors (bus errors) or peripheral faults.

Diagnostics 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.

Status The status indicators (yellow) indicate the status of the relevant input/output and the

connected I/O device.

Extended diagnostics 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 pe-

ripheral faults is sent to the control system with precise details of the error type and is

displayed using status indicators.

For information about the diagnostic and status indicators on a specific device,

please refer to the device-specific data sheet.
