IEC 61131 softPLC controllers models Z-TWS4-RT, Z-PASS2-RT-S, and R-PASS are essential components of EDGE computing-based industrial automation and offer a range of features that promote efficiency and reliability. These controllers act as digital sentinels of the factory, combining supervisory, diagnostic, processing, and data storage functions in a single compact unit. EDGE computing is a key component of these controllers and represents the ability to perform data processing close to the source, i.e., in field devices. This feature reduces latency and bandwidth utilization, optimizing data value and enabling faster analysis and response to real-time production situations.
Supervision is the first line of defense, as these controllers continuously monitor the health and performance of connected field devices, collecting real-time data and providing information for predictive maintenance.
Diagnostic capabilities are also critical. These controllers use advanced analytics to detect anomalies and deviations from expected behavior, enabling proactive troubleshooting.
Processing power is another key feature. Quest CPUs possess the computing power to perform on-site data processing operations, preprocessing data at the source before sending it to the cloud or central systems.
Real-time management of field devices is the hallmark of these controllers, enabling remote configuration, updating, and control of industrial equipment.
Security is paramount, with VPN connections to central control systems and strict access controls. They establish secure VPN connections to central control systems, encrypting data in transit. They also apply access controls, ensuring that only authorized personnel can interact with them, safeguarding against cyber threats. These gateways comply with the strictest cybersecurity standards, starting with compliance with penetration tests conducted according to OWASP, NIST 800 115 Risk Analysis, and IEC 62443. These CPUs serve as frontline intelligence, providing supervisory, diagnostic, processing, and data storage capabilities, contributing to efficient, responsive, and secure industrial operations. In addition, they support IEC 60870-101, IEC 60870-104, and IEC 61850 energy protocols, providing greater versatility and compatibility with power industry standards.
