• for the case where a measure is necessary or recommended in relation to the actually present process state (Z1, Z2, . . . , Zq) because of its classification, to generate an electronic message (T) depending on the calculated process state (Z1, Z2, . . . , Zq) and to output it by means of the output device (6), wherein it is preferably provided that the electronic message (T) contains an item of information as to which of the possible process states (Z1, Z2, . . . , Zq) that differ in relation to the process variable set (P) is actually present.

A method for monitoring a production facility containing a moulding machine functioning in moulding cycles and optionally at least one peripheral device, wherein, by means of a computing unit,
