Extracting Data from Machines
Build production IT systems on direct source data
explitia supports the complete process—from analyzing actual needs and creating an implementation roadmap to extracting data from machines, implementing an IT system and providing post-completion support.

What does extracting data from machines involve?
Extracting data from machines gives production IT systems access to information directly from industrial sources.

PLC controllers
Collect information stored and processed by machine controllers.

Sensors and actuators
Obtain measurements and signals directly from production equipment.

ERP and other IT systems
Use information already available in other systems operating in the plant.

Electrical signals
Acquire required data directly from available electrical signals.
The effects of extracting data from machines
Build production IT systems on data obtained directly from machines, sensors, actuators and other available sources.
-
Identify the signals and sources required by the IT system.
-
Check whether the required measurements exist.
-
Evaluate whether available measurements are sufficiently accurate.
-
Integrate information from several types of sources.
-
Use a common communication standard where possible.

Create a reliable data foundation for production IT systems.

Reliable source data
Use information obtained directly from production equipment and systems.

Integrated data sources
Combine information from different sources in one standardized model.

Appropriate automation
Automate data acquisition only where it has a business justification.

Engineering support
Use an interdisciplinary team to identify and acquire the required data correctly.
How does machine data acquisition work?

FAQ: Extracting Data from Machines
It should begin with an analysis of current processes and a pre-implementation audit. This helps identify the actual challenges of the plant and determine which data is required.
Data can be extracted from PLC controllers, sensors, actuators, electrical signals and other IT systems, including ERP.
Yes, but the need for integration should ideally be considered during the machine software development stage.
Yes. Interference with machine software may be restricted by warranty conditions, so integration requirements should be anticipated as early as possible.
It can involve reviewing software and electrical documentation, identifying the required signals and locating their sources.
The analysis identifies where a measurement is missing or insufficiently accurate, allowing the project team to plan the required changes.
Yes. Data from different sources can be integrated into one standardized model through an intermediary layer.
No. A common standard can often be used, but some projects require a dedicated integration solution.
No. The analysis should determine whether automation has a business justification. Some values may be entered manually.
