In production data acquisition (PDA), a distinction is made between different types of operating data. There is order data, personnel data, machine data and process data. Order data includes, for example, production data. This data, which is generated in the production process, is recorded using systems for plant data collection or machine data collection (MDC). Then they are passed on to so-called Manufacturing Execution Systems (MES) or also production control systems and processed. Machine data acquisition is also used for production planning and process automation in manufacturing. Machine data acquisition is part of production monitoring.
The MES systems listed in this current market overview enable real-time management. They control the manufacturing or production due to the direct connection to the production data acquisition and the machine data acquisition (MDC). They also control other processes that have an impact on the manufacturing process and support quality management. In addition to MES solutions, software for PDA and MDC is described here.
Production data acquisition, machine data acquisition and Manufacturing Execution Systems are among the key building blocks of digital manufacturing. They help manufacturing companies make processes more transparent, control production processes more effectively and evaluate data systematically.
Production data acquisition is the systematic collection of data from operational processes, especially from production. The aim is to capture relevant information on orders, personnel, machines, times and production progress in a structured way and make it usable for analysis.
Typically, PDA is used to collect the following data, among others:
The benefit of PDA lies in better oversight of the production process, more reliable documentation and well-founded analysis of actual conditions. This enables companies to analyse and optimise both operational workflows and organisational processes more effectively.
Machine data collection focuses on data provided directly by machines, systems or technical equipment. The emphasis is therefore not primarily on business processes, but on the technical condition and performance data of machines.
The following data are typically recorded:
The main difference from PDA is that MDC focuses more strongly on the machine itself. While PDA considers the operational process in a broader sense, MDC provides the technical real-time data for individual systems and production resources.
A Manufacturing Execution System is a software-based system for production control and monitoring at shop-floor level. It connects planning from the ERP or production planning and control system with operational implementation in production.
MES typically performs tasks such as:
An MES is therefore often the link between the commercial and operational levels. It ensures that production information does not remain isolated, but is available and evaluable along the value chain.
PDA, MDC and MES form the digital core of production, but they differ in focus: while PDA collects operational data and MDC provides technical machine data, the MES uses this information for active control and analysis of manufacturing.
In modern software solutions, these systems often merge into a single unit. The choice depends on the degree of digitalisation:
Standalone solutions: Ideal for a selective start or for connecting specific machines.
Integrated platforms: Useful for end-to-end processes and holistic production control.
In contrast to manufacturing-related systems (PDA/MDC/MES), higher-level systems have different priorities:
In modern manufacturing, seamless communication between ERP, PPS, CAQ and maintenance systems is essential to avoid media discontinuities and duplicate data entry. Open interfaces offer decisive advantages here: they enable flexible integration of machines, sensors and mobile devices. A high level of integration capability also conserves existing system resources, simplifies implementation and increases user acceptance through consistent data.
PDA, MDC and MES form the backbone of digital production. The decisive progress lies in the shift from manual to automated data acquisition directly from the system. This ensures high data quality with minimal effort. As enablers of Industry 4.0, these systems enable real-time monitoring and intelligent analyses, allowing companies to standardise their processes and significantly increase their responsiveness.
The implementation of PDA, MDC and MES systems is a complex undertaking that goes beyond the mere IT installation. The central hurdles can be divided into four areas:
In series production, the focus is often on monitoring machine runtimes, downtimes and scrap. It is important here that production processes run stably and efficiently and that deviations are recognised quickly.
In single-item and order production, the focus is on order progress, setup times and material consumption. Software helps keep track of changing orders and individual manufacturing steps.
In mechanical and plant engineering, transparency regarding project progress, production steps and resources is particularly important. The software helps to coordinate complex manufacturing processes more effectively and implement them on schedule.
In regulated or quality-critical industries, traceable documentation and traceability are crucial. In these environments, PDA, MDC and MES solutions help to capture process data cleanly and fulfil inspection and verification obligations.
