Services
Our industrial software engineering services
PLC programming & software development
Reliable, structured and maintainable PLC application software built with standardised function blocks and proven control methodologies across multiple automation platforms.
SCADA development
High-performance SCADA applications with intuitive operator interfaces, alarm management, historical data collection, trending and reporting.
HMI design & situational awareness
Abnormal Situation Management (ASM) and ISA-101 principles applied to KPI-driven HMI designs that improve operator decision-making and cut response times.
Manufacturing Execution Systems (MES)
MES solutions that connect plant-floor operations to business systems, giving real-time production visibility, performance monitoring and ERP integration.
Industrial IoT & digital transformation
Connected software that unlocks operational data for real-time analytics, asset performance monitoring and data-driven decisions.
Control system standards & documentation
Full functional design specifications, PLC and SCADA standards, configuration documentation and user manuals, so the system stays supportable long after handover.
Methodology
Engineering standards we build to
Repeatable standards are what make software quality consistent across projects, engineers and years.
Agnostic Control System Standards — our own OEM and platform-independent engineering standard, so the same methodology applies whichever vendor's hardware is on site.
Batch control — structured recipe and procedural control models for batch process applications.
Enterprise and control system integration — the framework for connecting plant-floor operations to ERP and business systems.
Industrial cyber security — security built into the control system design rather than added afterwards.
Human machine interface design — HMI graphics engineered so operators read plant state correctly under pressure.
Applied through
- Object-oriented design with reusable function blocks

Frequently asked questions
What is industrial software engineering?
The design, development and integration of automation software — PLC programs, SCADA systems, HMIs and MES solutions — used to control and monitor industrial processes.
What automation platforms does 4Sight OT Automation support?
We develop software across Schneider Electric, Rockwell Automation, Siemens, Mitsubishi Electric and AVEVA platforms, using vendor-independent engineering standards.
What are agnostic PLC and SCADA standards?
Agnostic standards let the same engineering methodology, function blocks and design approach apply across multiple automation platforms, which improves consistency, quality and maintainability.
Do you follow industry engineering standards?
Yes. Our software engineering aligns with ISA-88, ISA-95, ISA-99 and ISA-101, supported by a TÜV ISO 9001:2015 certified quality management system.
Can you integrate automation software with business systems?
Yes. We integrate MES and control systems with ERP and business intelligence platforms for real-time operational visibility and data-driven decision-making.
