Application fault, all in one applications. Start-up of the new option board. Fault appears, when internal SPI bus is overloaded or broken. SPI bus communicates via slots B to E.
-Reset the fault. -If the fault appears, when new option board has been plugged, initialization state is active on the option board, but it does not reach RUN state. Reason might be the wrong data in the option board EEPROM. -Check the RUN status on each option board. -If the status is RUN: application might communicate with option board too many times/slot or application is too heavy. -If the status is NOT RUN: there is hardware fault on the control board or on the option board SPI communication.
