SIMATIC HMI Panels
SIMATIC HMI panel selection usually breaks on the first split between basic operator interaction, broader machine visualization, and the newer Unified runtime path. The wrong branch is often chosen when screen size is compared before runtime depth, engineering workflow, and platform direction are clear.
This page separates Basic Panels, Comfort Panels, and Unified Panels before exact model comparison. That keeps the shortlist focused on the right HMI branch instead of treating all SIMATIC panels as screen-size variants.
Compared Branches
3 HMI lines
Basic, Comfort, and Unified panels are different runtime paths, not just different displays.
Main Decision
Runtime depth
The panel branch usually turns on visualization scope and platform direction first.
Common Risk
Wrong platform
Teams often narrow by screen size before they settle the right HMI family.
Typical Trigger
Retrofit or new UI
Most branch decisions begin with either a panel replacement or a new operator interface.
Understand the category
Start here to see what belongs in this family, which installation contexts it typically supports, and which brands are represented before you narrow down to a specific series.

Compare related series
Compare the child series on runtime scope, visualization depth, engineering expectations, and long-term platform direction. Those differences usually decide the HMI family before screen size or exact panel dimensions matter.
Basic Panels are the simpler operator-interface branch, Comfort Panels cover broader classic SIMATIC visualization work, and Unified Panels enter when the project needs the newer Unified runtime path.

SIMATIC HMI Basic Panels Entry-level Siemens HMI panel family for straightforward operator interface tasks. Open series | Machines that need a simple operator panel without moving into the richer HMI branches. | Entry-level operator panels for routine machine visualization and control. | Basic | Best read as the basic SIMATIC HMI branch before choosing the exact panel size. | Useful for straightforward Siemens HMI standardization and installed-base replacements. | 2 products |
SIMATIC HMI Comfort Panels Mid-range Siemens HMI panel family for richer operator interface and machine-visualization work. Open series | Machines that need a stronger HMI branch than Basic without moving to Unified. | Mid-range operator panels for broader Siemens machine-HMI deployments. | Comfort | Best read as the Comfort HMI branch before choosing the exact panel size and interface mix. | A strong Siemens HMI branch for established machine-panel standardization. | 2 products |
SIMATIC HMI Unified Panels Siemens Unified HMI panel family for projects standardizing on the Unified platform path. Open series | Projects that deliberately want the Siemens Unified HMI platform path. | Unified-runtime operator panels for newer Siemens HMI platform deployments. | Unified | Best read as the Unified Siemens HMI branch before choosing the exact display and interface format. | A forward-looking Siemens HMI branch for projects standardizing on the Unified platform. | 2 products |

How to narrow the options
Start with the engineering constraints that actually reduce the option set, then move from those checkpoints into the most relevant series, guides, and tools.
Runtime and Visualization Depth
Decide how much interface scope, visualization depth, and runtime flexibility the project needs.
Platform Direction
Separate classic panel continuity from projects that should move into the Unified branch.
Retrofit Versus New Design
Keep panel replacement logic separate from new-machine interface design so the branch choice stays clear.
Step 1
Is the project a panel replacement or a new interface design?

Step 2
Does the project need a simpler operator panel or a broader visualization branch?
Signals to check
Step 3
Is long-term platform direction already a factor?

Common selection mistakes
Use this checklist to avoid the common mismatches around compatibility, deployment style, and lifecycle assumptions that usually surface late in a project.
Comparing HMIs by screen size before runtime branch
highWhy it matters
The shortlist can stay on the wrong platform even when the screen format looks acceptable.
Safer route
Choose the HMI family by runtime and platform direction first, then compare exact panel sizes.
Using retrofit continuity to define every new HMI decision
mediumWhy it matters
Replacement habits can keep new projects on an older branch longer than necessary.
Safer route
Separate installed-base continuity from new visualization design until the family choice is settled.
Treating Basic, Comfort, and Unified as adjacent screen variants
mediumWhy it matters
The project can miss a more important runtime or engineering mismatch.
Safer route
Read the series first as different HMI branches, not just adjacent display options.
