SIMATIC HMI
Operator Panels
Machine visualization and operator interfaces for new systems and modernization projects.
Honghao helps identify panel families, display size, communication compatibility and replacement paths. For integrated projects, HMI supply can be combined with PLC selection, control-cabinet assembly and programming coordination.

Common SIMATIC HMI searches
Decisions that change the BOM.
Review these points before choosing a model name or requesting a replacement.
01How do I select a SIMATIC HMI screen size and family?
SIMATIC HMI selection
Review mounting cut-out, viewing distance, number and density of controls, alarm and trend needs, PLC protocol, user management, remote access, environment, software platform and replacement path. Screen size alone does not define compatibility.
Review Unified Comfort Panels02Can an old HMI project be used on a Unified Panel?
SIMATIC HMI migration
A conversion assessment is required. Check the original engineering project and version, scripts, faceplates, fonts, recipes, archives, communication drivers, user management and unsupported functions. Budget time for redesign and acceptance testing.
See the retrofit workflow03What should be included in an HMI replacement RFQ?
Siemens HMI replacement RFQ
Send photos of both labels, the full old article number, project backup, software version, panel cut-out, PLC type, communication, language requirements and a list of critical screens or functions. State whether programming and site commissioning are required.

The information needed for a technically usable offer.
What should I send for a SIMATIC HMI quotation?
SIMATIC HMI quotation
Send the full article number for replacements. For a new application, provide display, controller, functions, migration, quantity, destination and required delivery date. Honghao will identify assumptions before confirming the BOM.
Send product or application dataHow does Honghao verify SIMATIC HMI compatibility?
SIMATIC HMI compatibility check
The review checks the complete article number, product generation, required accessories, electrical and communication interfaces, lifecycle status and the surrounding system. Final ratings remain tied to current manufacturer documentation and the approved BOM.
See the BOM verification methodCan SIMATIC HMI products be supplied inside a complete control panel?
SIMATIC HMI control panel
Yes, when the contracted scope includes panel engineering. The design basis should define power, protection, environment, interfaces, drawings, programming responsibility, FAT and export documentation before assembly.
