Schneider Electric PLC Programming & Modicon Automation
Comprehensive Schneider Electric Modicon PLC programming, EcoStruxure machine automation, Harmony HMI integration, and zero-risk legacy migrations engineered to British standards.
High-Performance Schneider Electric Automation Built for Industrial Reliability
Schneider Electric Modicon programmable logic controllers represent a gold standard in modern industrial process and machinery control. Combining powerful cyclic processing with open Ethernet communications, Modicon systems drive mission-critical equipment across UK manufacturing, utilities, and material handling.
At MASK Control Systems, our controls engineers deliver complete Schneider automation solutions. Whether you require bespoke PLC software programmed from concept, an intelligent Harmony HMI interface, seamless variable speed drive integration, or a planned migration from obsolete TSX hardware, we build systems that maximize reliability and eliminate unplanned downtime.
Ideal for small standalone automated machines, basic material handling, and dedicated pumping stations requiring compact footprint and simple programming.
Tailored for high-performance machines, multi-axis motion control, and distributed architectures requiring dual-channel Ethernet networking.
Designed for connected machines needing cloud communication, high-speed motion, and embedded cybersecurity (IEC 62443 compliance).
The world leading Ethernet-programmable automation controller (ePAC) engineered for continuous process, utilities, and safety-critical installations.

From clean-sheet machine code development to complex multi-station SCADA and obsolete controller upgrades, we cover every stage of your automation investment.
Custom Modicon PLC Programming
Tailored PLC programming engineered for bespoke manufacturing machinery, automated packaging lines, and continuous batch processes using modular, IEC 61131-3 logic.
Control System Architecture & Hardware Design
Turnkey design of complete Schneider Electric automation hardware systems, power distribution, and multi-node industrial fieldbus topologies.
EcoStruxure Software Engineering
End-to-end software development utilizing Schneider Electric EcoStruxure Machine Expert, Control Expert, and Machine Expert - Basic suites.
Harmony HMI & SCADA Systems
Development of intuitive touchscreen operator interfaces and plant supervisory systems delivering real-time control, alarming, and operational clarity.
Legacy Modicon Migration & Modernization
Strategic migration of obsolete legacy systems (Modicon TSX Micro, TSX Premium, and Quantum) to modern, supported M340 and M580 ePAC controllers.
Diagnostics, Fault Finding & Support
Emergency on-site troubleshooting, remote diagnostics, and preventative maintenance for Schneider Electric PLC systems across the UK.
Real-World Problems We Solve for Schneider PLC Users
Manufacturers and plant engineers across the UK rely on MASK Control Systems to overcome persistent automation challenges and legacy limitations.
Obsolescence of TSX Premium or Quantum
Aging legacy Schneider hardware that is no longer manufactured, with escalating failure risks and scarce, costly second-hand spares.
We modernize obsolete systems to supported Modicon platforms with pre-tested software conversion and minimal production cutover time.
Intermittent Modbus or Ethernet Communication Drops
Unexplained network dropouts, packet collisions, or communication timeouts between PLCs, variable speed drives, and SCADA.
We audit industrial network health, install managed Ethernet switches with RSTP/MRP loops, and correctly configure fieldbus timing.
Software Lockouts and Missing Documentation
Machine bought without source code, password-locked programs, or missing electrical schematics after previous engineers departed.
Our controls engineers retrieve uploadable logic, reconstruct project files, and supply full updated CAD schematics.
Uncoordinated Multi-Vendor Equipment
Difficulty synchronizing Schneider controllers with third-party Siemens, Omron, or robotic controllers across the factory.
We deploy standardized Modbus TCP, Ethernet/IP, and OPC UA bridges to create seamless bidirectional handshakes.
Emergency Breakdowns & Lack of Fast Support
Line shut down unexpectedly due to an internal PLC trip, corrupted memory card, or failed module with no local specialist available.
We connect remotely via secure VPN within minutes or dispatch experienced controls engineers directly to your UK facility.
Our 6-Step Schneider PLC Engineering Process
Every project follows our rigorous quality framework, from initial functional specification through to in-house testing and final site validation.
System Audit & Scope
Detailed review of existing hardware, field instruments, safety zoning, and operational production goals.
Hardware Architecture Design
Developing complete Schneider Electric controller configurations, network maps, and BS EN 61439 electrical CAD drawings.
Software Engineering
Writing modular, documented PLC logic in EcoStruxure along with intuitive Harmony touchscreen interface screens.
In-House Simulation & FAT
Comprehensive offline simulation and Factory Acceptance Testing at our Devon panel workshop to verify every sequence.
On-Site Commissioning & SAT
Live plant integration, I/O verification, safety trip testing, and cycle optimization under actual operating conditions.
Documentation & 24/7 Support
Complete As-Built documentation handover, program backups, maintenance training, and ongoing SLA technical support.
