Detailed study of the process information is required to determine the operational parameters for data acquisition.
Explain the difficulties in digital communication protocols across different companies and cloud server system setup.
Explain the complete solution from the PLC triggered inputs to the MVX units – Internet switches – cloud server – analysis – reports and customer server access.Case study of a defect detected and corrective action taken to potentially avoid a premature bearing failure.
