Sequence Link
A platform for hosting interactive functional descriptions. Navigate complex sequences, understand system logic, and keep your team on the same page.
What is Sequence Link?
Sequence Link turns your functional descriptions into interactive, navigable documentation. Instead of flipping through static PDFs or deciphering PLC code, your team can step through sequences, understand conditions and interlocks, and see exactly how your automated systems are designed to operate.
Currently in development. Talk to us about early access.
Who it's for
Control systems engineers who need a clear, navigable reference for PLC and SCADA logic during development and commissioning
Maintenance technicians troubleshooting equipment and needing to understand the sequence logic behind automated processes
Operations teams who want to understand what the system is doing and why, without reading raw PLC code
New team members learning how complex automated systems work and needing structured documentation to get up to speed
Problems it solves
Functional descriptions buried in outdated PDFs or Word documents
Critical system logic locked in the heads of senior engineers
Difficulty understanding complex PLC sequences without stepping through code
No single source of truth for how automated systems are supposed to work
New staff taking months to understand system logic because documentation is scattered
Key capabilities
Interactive functional descriptions
Host your functional descriptions in an interactive format. Navigate through sequences step by step, understand conditions and interlocks, and see how your system logic fits together.
Sequence visualisation
See complex PLC and SCADA sequences laid out clearly. Follow the logic flow, understand transitions between states, and identify where conditions are met or blocked.
Team collaboration
Give your entire team access to the same source of truth for system logic. Operators, engineers, and maintenance staff all working from the same functional description.
Version tracking
Track changes to functional descriptions over time. See what changed, when it changed, and why. Maintain a clear history of your system logic as it evolves.
Searchable documentation
Find the sequence or interlock you need in seconds. Search across all your functional descriptions by keyword, equipment tag, or step number.
Offline access
Access functional descriptions on-site even without reliable internet. Your team can reference system logic during commissioning, maintenance, or troubleshooting.
How teams use Sequence Link
During commissioning
Walk through each sequence step by step with the client and operations team. Everyone can see the logic, understand the conditions, and verify the system behaves as designed. Questions get answered on the spot instead of weeks later.
Troubleshooting faults
When a sequence stalls or behaves unexpectedly, your team can pull up the functional description and trace the logic. See which conditions need to be met, what interlocks are active, and where the process is stuck.
Training new operators
New team members can explore the system logic at their own pace. Step through sequences, understand what each phase does, and build confidence in how the plant operates before they need to manage it themselves.
Managing modifications
When system logic changes, update the functional description in Sequence Link and everyone has the latest version. No more outdated printouts on the control room wall or PDFs that nobody can find.
Part of the Process Link Platform
Sequence Link integrates with the broader Process Link Platform. Combine interactive functional descriptions with shift handovers from Shift Link and asset documentation from Dossier to give your team a complete operational toolkit.
Make your system logic accessible to your whole team.
