Module status displays
Three LEDs at the front of the CU320-2 PN provide information about the state of the module.
They indicate the states when powering up and in operation:
● If an error occurs, the power-up is terminated and the LEDs indicate the cause of the error.
● At the end of an error-free power-up, all LEDs are switched off briefly.
● After power-up, the LEDs are controlled via the loaded software.
