PLC software
New programmes, migrations and upgrades across major vendor platforms, written for dependable operation and straightforward maintenance.
PLC, SCADA, HMI & industrial software
Reliable control, useful data and software that works for your team.
We design and integrate dependable PLC software, operator interfaces, plant-wide SCADA and specialist industrial applications, with control architecture and data interfaces built around the process.

What we deliver
PLC, HMI, SCADA and software designed as one control layer.
We combine maintainable control software, useful operator information and secure OT integration around the process requirement.
SCADA & HMI
Operator interfaces and supervisory systems that prioritise the right information, alarms and controls for each user.
Industrial software
PC, server and embedded applications for data logging, reporting, traceability, databases and specialist workflows.
Control architecture & networks
Controllers, distributed I/O, drives, panel interfaces and plant networks defined as a coherent, supportable system.
Upgrades & migrations
Assess legacy platforms, recover existing logic and data, and plan staged migrations that manage downtime, testing and rollback.
Engineering basis
Structured for dependable operation, clear diagnostics and recovery.
Controller, network and software architecture is developed alongside operating modes, alarms, data interfaces, backups and the long-term support model.
Control architecture
Controller selection, I/O distribution, network topology, panel interfaces, redundancy needs and recovery strategy are defined from the process criticality and support model.
Software structure
Sequences, permissives, interlocks, alarm handling, operating modes and manual controls are documented and implemented in a maintainable, modular structure.
Operator information
HMI and SCADA views are organised around tasks, plant states, alarm priority, trends, recipes and diagnostics rather than simply mirroring PLC tags.
Data & OT integration
Interfaces to historians, databases, reporting systems and plant networks are scoped with ownership, time synchronisation, backups and support access considered from the outset.
