System-integrated measurement simplifies power management
February 2, 2021
A highly efficient power measurement chain provides a range of solutions from the sensor to the cloud. These include capturing the physical value with new SCT current transformers, to the IoT Coupler and finally to cloud-based data analysis. A broad spectrum of power measurement terminals covers requirements.
Root of Trust in EtherNet/IP devices using CIP Security
February 1, 2021
CIP Security for EtherNet/IP can assist manufacturers in preventing security breaches. The CIP Security standard requires authentication and integrity of EtherNet/IP messages. It also requires both Scanners and Adapters to be authenticated, and implements message encryption to ensure integrity and privacy.
Safety over EtherCAT conformance testing
November 3, 2020
To formally confirm a high level of safety, the manufacturers of EtherCAT devices must meet requirements during development, testing and implementation to ensure the safe operation of products. A wide range of support services are available including tools, tests, documents and consultation.
Use Cases for a CIP Companion Specification for OPC UA
September 7, 2020
An OPC UA companion specification for CIP to OPC UA Gateways is based on assumptions that the cloud interface will use an OPC UA information model; it will use OPC UA transport mechanisms (MQTT, AMQP or HTTPS) and the cloud interface will use OPC UA defined cybersecurity roles, authentication and…
PROFINET Over Industrial WLAN Infrastructure
September 1, 2020
Two key challenges need to be addressed when building a stable PROFINET application over a WLAN infrastructure. The selected WLAN solution must support L2 forwarding in different configurations, and wireless latency and jitter need to be minimized to meet the requirements of the PROFINET application.
Securing network devices with the IEC 62443-4-2 standard
July 1, 2020
As devices are being constantly added to networks, device security is of paramount concern to asset owners. Complete system-level security must be built upon the foundations that consist of each individual component’s security functions, along with cybersecurity standards such as IEC 62443.
Time synchronization to improve determinism and response time
July 1, 2020
Synchronizing I/O tasks with application execution can result in improved application response times. In an ever-changing world where vendors are striving to eke out every bit of performance from their PLC systems, time synchronization is a method to add to the list of potential future upgrades.
Single-Pair Ethernet for constrained devices
July 1, 2020
Single Pair Ethernet offers reduction in wiring, node cost, size and power consumption, delivering communication and power over a single pair. New operational concepts are being developed to drive EtherNet/IP deployment to low-end constrained, in-cabinet devices such as contactors and push buttons.
How Industrial Linux enables distributed IIoT applications
March 9, 2020
Distributed IIoT applications require robust, secure operating systems to preprocess mission-critical information before transmitting to the cloud. Capable of addressing development, remote maintenance, data protection and support, Industrial Linux distributions have become popular edge gateway operating systems.
Industry 4.0 communications for process automation
March 9, 2020
Digitization is shifting toward the sensor in the era of Industry 4.0 process automation. Implementation of smart sensors that can be integrated anywhere in a complex network allows them to pass on the digital form of recorded physical quantities over the network, versus digitizing analog signals transmitted to a controller.
