Data acquisition


instance, capturing data from Enterprise Resource Management (ERP) or Manufacturing Execution Systems (MES) systems for consideration alongside Operational Technology (OT) data from the factory floor. Data collected by IT systems can be used to streamline production processes, fix critical issues faster and make better informed decisions - but only if it is collected, transmitted and processed effectively and


securely. The most effective systems will be able to operate across both of these technology spheres. In addition, a software platform doesn’t only gather data from different hardware and IT systems but do also need to provide data in an open format and accessible for third parties, e.g. through a REST API. Modern SCADA can operate like a data hub or, as you could also name it, as an OTIL (Operation Technology Integration Layer).


APPLYING SCADA FOR INDUSTRY 4.0 Now we understand the potential of modern SCADA systems - how do engineers use this technology in their digitalisation journey? On its most basic level, a SCADA system lets an operator verify that its machinery is operating correctly. However, modern systems should enable an operator to use SCADA data to determine how to make improvements or adjustments to equipment to maximise productivity or efficiency. At the beginning of any digitalisation project, a manufacturer should consider its data sets and use them to determine smart goals. Is achieving better energy efficiency a key company goal? The platform should be capable of identifying areas of high energy usage, and this is where that organisation should start their process. Is improved capacity to produce customised projects a goal? In this case, data on equipment availability will be key. In order for the company to make informed decisions on digitalisation, having access to a full facility of data sets is key. Without having clear visualisation of all the data produced from a facility - whether this is related to energy usage, productivity, downtime or something else - it is impossible to embark on an informed Industry 4.0 journey. In fact, proper investment in data collection technology should come before any other smart factory investment - including any hardware.
