MES-Definitionen

According to the common definition, machine data collection (MDC) includes all information that describes the current performance of the machine. This includes the up and downtimes, the cycle rate or ratherspeed of the machine and the produced quantity. All of these are the basic input for the machine data. This information can be easily gathered from registering part made of pulses available from the machine control or from suitable sensors.

In a typical MDC, this information is supplemented at least by down codes, which classify the causes of machine downtimes into predefined categories. Normally, a machine terminal is required for entering down codes. An automatic input of digitally available fault messages from the machine control system is also common.
