Ifm highlights the value of IO-Link connectivity
Industry 4.0 promises a connected manufacturing environment where machines, systems and people can share information in real time. Achieving that vision depends on one critical requirement: reliable, structured data from the shop floor.
Mark Jones, managing director of ifm New Zealand, says the role of sensors has changed significantly as manufacturers pursue greater automation and visibility across their operations.
“Traditionally, sensors were simple devices providing on/off signals or analogue values. No context, no diagnostics and no ability to communicate beyond a basic measurement,” says Jones.
“Industry 4.0 changes the expectation, where every device becomes a source of intelligence.”
According to Jones, IO-Link addresses this challenge at the field level by transforming sensors and actuators into digital devices capable of transmitting process values, diagnostics, parameters and status information in real time.
“Instead of a single signal, the factory gains a continuous stream of structured data,” he says.
Jones says this provides the foundation for the end-to-end data flow required to support technologies such as advanced analytics, artificial intelligence and predictive maintenance.
“It provides a seamless connection from field devices through the control layer and up into higher-level systems such as MES, ERP or the cloud. Without this continuity, advanced analytics, AI and predictive maintenance simply do not function.”
The technology is already being applied in New Zealand manufacturing environments, including a North Island dairy processing facility, with systems integration support provided by plant builder Pacific Process.
Standardisation is another advantage. Jones says IO-Link replaces the traditional mix of proprietary interfaces and wiring systems with a global, vendor-independent standard, allowing devices from different manufacturers to communicate using a common protocol.
The technology also supports greater operational transparency through bi-directional communication, enabling devices to report condition information, identify faults early and allow remote parameter changes.
“This enables predictive maintenance, reducing downtime and helping operations move from reactive to proactive maintenance strategies,” says Jones.
He says IO-Link delivers these capabilities through a simple and scalable architecture using standard cabling and straightforward integration into existing systems.
“IO-Link is not just another communication interface. It is the digital foundation at the field level, turning raw signals into usable data and connecting that data to the wider manufacturing system.”
