LED status displays
After having been switched on, the CI 772 PROFIBUS module performs a self-test
during power-up. If the test is successfully performed, the yellow LED RDY lights
up, if not, the LED starts to flash and the initialization is aborted. If the LED RDY
does not light up at all, the PROFIBUS module is probably defective. During
initialization, with newly configured modules or after a change of the operating
mode, all LEDs may light up briefly before reaching the defined status.
