Diagnostics alarms

Actions after a diagnostics alarm
There can be more than one diagnostics alarm at the same time. Each diagnostics alarm
initiates the following actions:
• The ERROR LED of the interface module flashes red.
• Diagnostics are reported as diagnostic error interrupts to the CPU of the IO controller and
can be read via data records.
• Incoming diagnostics alarms are saved to the diagnostics buffer of the I/O controller.
