LED Diagnostic Indicators of INTERBUS Devices For quick and local error diagnostics, all INTERBUS devices have LED diagnostic and status indicators. The LED diagnostic indicators (red/green) indicate the type and location of the error. A device is functioning correctly if all of the green LEDs are on. The LEDs listed below are typical for INTERBUS devices, but not all of them are on every device. Depending on the module type, additional indicators can also indicate the status of the module. For additional information about a specific module please refer to the corresponding data sheet.
