What does production data acquisition mean?

Production data acquisition (PDA) is a collective term for the acquisition of actual data on conditions and processes in companies. This data can be integrated into Plant Information Management Systems, Manufacturing Execution Systems or SCADA systems. As a rule, data is recorded as follows:

• Centrally via workstations at central PPS systems,
• decentralized, for example via workstations at decentralized control stations or BDE systems,
• via data collection terminals or
• through direct machine data acquisition.

The identification of the “PDC object”, for example a work process for which a PDC message is to be recorded, is often carried out with barcode support. In addition to modern methods, there is also a paper-based approach that uses writing objects to transfer characters or even primitive symbols (such as tally marks) to the paper. PDC systems manage a variety of data from different areas:

• Operating data (organizational & technical operating data)
• Order data (production data such as times, quantity, weight, quality, number of items or work progress, order status, feedback on order-related work)
• Personnel data (attendance and working hours as well as other data for calculating wages, wage costs, access control, etc.)
• Machine data (switching frequency, interruptions and running times of machines, quantities produced, messages and faults, interventions by operating personnel, maintenance data, consumption of materials, energy and auxiliary materials or measurements of the temperature in storage rooms or production, immission values, etc.).
• Process data (quality, process parameters, setting data, etc.)
