Application: Factory Automation Solution for Existing Machine Equipments
The customer wanted to monitor the machines’ operating status. However, most old machines do not have communication ports, and for those that do, it is difficult to obtain the communication protocols from suppliers. Therefore, various sensors were installed in the machines for signal acquisition, with the AD-ADAM-6250 utilized to obtain the status of the machines (e.g., running, shut down, idle, breakdown) and stack lights.
AD-ADAM-6250 modules were installed on each machine. A daisy chain configuration was adopted to connect neighbouring modules in order to minimize on-site wiring. Collected data were then aggregated on a local AD-UNO-2184G automation computer. Because the workshop was far from the control centre, an AD-EKI-2525 switch was adopted to forward the data to the control room.
The machines’ operating status can then be collated into reports in order to view the efficiency of on-site equipment. The system has an alarm mechanism and fault button so that the health of the equipment can be monitored; this has facilitated timely repair and maintenance planning, thus improving the equipment life span, reducing the number of equipment failures, and saving more than 20% on hardware costs.
