Profibus module FI 830F state led display orange and is blinking what is the cause?
My HPU PLCs both failed so i reset them one after the other, primary failed to reboot and secondary rebooted and came back online with profibus module FI830F displayed blinking orange led. My message list tells me PLC A failed and Secondary has an invalid operating system what could this mean?
please do a controller firmware update and Profibus Module firmware update using the Freelance Settings Tool. Run it as administrator. Update both your controllers. Then connect the engineering tool and do a download whole station to the redundant controller.
