Depending on the method of communication with machines, we have various options for monitoring the machine park. In its most extensive form (e.g. when integrating with a PLC), the system collects information on binary states: work, no work, auto mode on, manual mode on, safety off, door / cover opening and many other signals that the customer would like from the machine monitor. The system can also collect analog data: temperatures, feeds, revolutions, pressure, torques, cycles and other variables saved in the PLC of the machine. In addition, the system can archive information in the form of logs on: a running program or an established tool. In the least developed form of machine park monitoring (machine sensing or receiving electrical signals), the system collects basic information: work, lack of work, quantities produced / cycles worked.
