Ignition ships two visualization modules — Vision and Perspective — and "which one should we use?" is one of the most common questions we get from teams starting a project. They both build operator screens on the same Ignition gateway, tags and history; the difference is how those screens are delivered and where they run. Here's how we decide.
What each one actually is
Vision is the original module: a thick desktop client launched from the gateway (Java), purpose-built for fixed plant-floor HMI stations and control-room workstations. It's mature, fast on a wired LAN, and excellent for always-on screens running on dedicated panels.
Perspective is the modern module: pure web (HTML5) that runs in any browser and as a native mobile app, with responsive layouts that adapt from a wall display down to a phone. It's built for access from anywhere, touch devices, and modern UX — and it's where Inductive Automation is focusing new investment.
When Vision is the right call
Reach for Vision when the screens live on fixed, wired, always-on stations — dedicated HMI panels and control-room workstations — and there's no real need for phone/tablet or off-site access. It's also the pragmatic choice when you already have a large Vision project that works: there's rarely a business case to rebuild a stable HMI just to change the rendering technology. Some teams also prefer its straightforward desktop window/templating model for dense, static control screens.
When Perspective is the right call
Choose Perspective for almost any new project where access matters: web and mobile clients, remote sites, on-call staff, dashboards for managers, or anything you want to reach without installing a client. It shines for remote and distributed monitoring (pump stations, water districts, unmanned plants), for responsive screens that work on a phone in the field, and for modern, branded operator UX. If you're greenfield, Perspective is usually the default unless a specific constraint points to Vision.
Do you have to pick just one?
No — and you often shouldn't. Vision and Perspective run side by side on the same gateway against the same tags. A common pattern is Vision on the fixed plant-floor HMIs that already exist, with Perspective added for mobile access, remote sites and management dashboards. You get modern reach without ripping out screens that work.
Migrating Vision to Perspective
There's no one-click converter, and that's fine — Perspective's responsive, component-based model is different enough that a thoughtful rebuild beats an automated translation. The good news is that the hard part — tags, UDTs, history, alarms, device connections — is shared, so a migration is really just re-building the screens on top of an unchanged data layer. We treat it like any modernization: rebuild the high-value screens first, run in parallel, and phase the rest. (It's the same disciplined approach we use when replacing Wonderware with Ignition.)
Our recommendation
For new work, start with Perspective unless a fixed-panel, wired-only HMI clearly calls for Vision. For existing Vision systems, keep what works and add Perspective where mobility and remote access pay off. The platform is the same underneath — the right answer is about where and how people need to see the screens.
Where we come in
We design and build both Vision and Perspective applications on Ignition — new projects, Vision-to-Perspective modernizations, and mixed deployments — on-site across California's Central Valley and remotely nationwide. To talk through which fits your plant, get in touch or see our Ignition development services. When you outgrow the stock Perspective table, our Perspective DataGrid Pro module picks up where it stops.
Frequently asked questions
Should I use Perspective or Vision for a new project?
Usually Perspective, for web and mobile access and responsive layouts — unless you specifically need fixed, wired desktop HMI panels, where Vision is a strong fit.
Can I run Vision and Perspective together?
Yes. Both run on the same gateway against the same tags. Many plants keep Vision on the floor and add Perspective for mobile and remote access.
Is there an automatic Vision-to-Perspective converter?
No. Screens are rebuilt (tags, history and alarms carry over unchanged), which is also a good chance to modernize the layouts.
