TwinCAT PLC++ Leads New Generation of PLC Technology with 3x Performance Boost

TwinCAT PLC++ Leads New Generation of PLC Technology with 3x Performance Boost

The industrial automation landscape continues to evolve rapidly as major manufacturers unveil groundbreaking innovations in programmable logic controller (PLC) technology. Beckhoff’s newly released TwinCAT PLC++ represents a paradigm shift in control systems, delivering up to three times faster execution speed compared to its predecessor while maintaining full compliance with IEC 61131-3 standards.

Beckhoff TwinCAT PLC++: DevOps Meets Industrial Control

TwinCAT PLC++ seamlessly integrates into the established TwinCAT environment while introducing advanced compiler technology that significantly optimizes both development and runtime performance. The new system leverages nearly three decades of experience from over 20,000 TwinCAT users worldwide, incorporating their feedback to enhance user interface intuitiveness and functionality.

Key performance metrics demonstrate remarkable improvements:

• Runtime Performance: Identical control code executes 1.5x faster than TwinCAT PLC, with optimization options achieving up to 3x speed improvement
• Development Efficiency: Reduced project loading times and improved conversion workflows
• Project Cycle Time: Significantly shortened development-to-deployment timeline accelerates time-to-market

The integration with TwinCAT MC3, Beckhoff’s next-generation motion control technology, enables efficient control and monitoring of complex applications, further enhancing customer solution competitiveness.

NERC Activates Emergency Grid Monitoring Following Iran-Linked PLC Cyber Attacks

In a concerning development for critical infrastructure security, the North American Electric Reliability Corporation (NERC) has initiated active grid monitoring protocols after CISA confirmed that Iran-linked threat actors successfully disrupted critical U.S. infrastructure through PLC exploitation. The joint advisory details ongoing attacks targeting energy, water, wastewater, and government sectors.

Attackers leveraged Rockwell Automation’s Studio 5000 Logix Designer software to establish trusted connections with victim PLCs, specifically targeting CompactLogix and Micro850 models. The campaign exploited internet-exposed operational technology (OT) systems, manipulating project files and altering data displayed on HMI and SCADA dashboards.

Technical indicators reveal a sophisticated methodology:

• Malicious traffic targeting ports 44818, 2222, 102, 22, and 502
• Dropbear SSH software deployed for persistent remote access
• Code injection separating textual code from binary bytecode during compilation
• Approximately 50-80% of U.S. grid control endpoints rely on vulnerable PLCs

This escalation marks a shift from opportunistic scanning to targeted, disruptive operations against critical infrastructure, highlighting the urgent need for enhanced cybersecurity measures in industrial control systems.

Siemens Announces S7-200 SMART G2 Launch and ET 200PA SMART+ Upgrade
