Controls modernization
Legacy PLC, HMI, drive and network assessment followed by phased migration planning, engineering and commissioning support.
Delivery approach
A modernization project should reduce obsolescence without introducing unmanaged production risk. AranVision documents the installed system, identifies critical dependencies and develops a migration path that can be reviewed, budgeted and executed in controlled stages.
Scope clarity
Modernization begins with evidence about the installed system. Drawings, programs and physical equipment are reconciled because each may describe a different revision. Interfaces to remote I/O, drives, safety, HMI, historians, databases and third-party machines are documented before replacement options are compared.
The preferred architecture is selected against production risk, maintainability, lifecycle support and the available outage—not only hardware availability. A phased plan can preserve selected field devices or interfaces while creating deliberate points for testing and rollback. Budget estimates identify assumptions so later discovery does not appear as unexplained scope growth.
Every engagement begins with a written boundary for access, production impact, client-supplied information, approvals and third-party responsibilities. Recommendations are tied to the evidence available at the time. If field discovery changes a critical assumption, the effect on scope, testing and acceptance is reviewed before the work proceeds.
Project readiness
These checkpoints keep responsibilities visible and prevent important interfaces from becoming late-stage surprises.
Project outcomes
Programming, controls documentation, integration, testing and commissioning support are delivered within the agreed responsibility matrix. Any regulated professional engineering, electrical contracting, panel certification or authority approval is identified separately and assigned to the appropriately licensed or authorized party.
Typical deliverables
The final scope is adjusted to the installed system, project stage, client standards and site responsibilities.
Installed-system and backup assessment
I/O, network and interface inventory
Obsolescence and risk register
Target architecture and migration plan
Budgetary work-package definition
Cutover, rollback and commissioning plan
Delivery method
Collect backups, drawings, hardware, communications, field interfaces and known operational issues.
Separate what must change, what can remain and how legacy and new equipment will coexist during transition.
Establish test strategy, outage sequence, acceptance criteria, backups and rollback decisions before site execution.
Common questions
Yes. A phased approach is often preferred when production windows, budget or interface risk make a single cutover impractical.
Yes. A discovery and assessment package can define condition, risk, options and next-step priorities without committing to a full implementation.
