The alarm is an important monitoring element. The machine operator is alerted if a value goes above or below a certain threshold, i.e. if there is a problem on the machine, and can retrieve additional information about the condition of his machine and remedy problems before a standstill occurs. The alarm can assume different forms, depending on which rules were defined for certain degrees of the threshold violation. The alarm notification can be both an SMS or an e-mail, or trigger a service request.
