Pro-face GP4000 vs Siemens Unified Comfort: HMI Touch Screen Migration & VESA Mounts

Pro-face GP4000 vs Siemens Unified Comfort: HMI Touch Screen Migration & VESA Mounts

Human-Machine Interfaces (HMIs) bridge machine operators with programmable logic controllers. In plant retrofits, upgrading legacy resistive touch screens to modern multitouch capacitive panels is essential for SCADA and IIoT data visualization.


1. Pro-face GP4000 vs SIMATIC HMI Unified Comfort

  • Pro-face GP4000 (GP-4501T / GP-4601T): Renowned for protocol agility (supports over 800 communication protocols with multi-vendor PLC networks via GP-Pro EX).
  • Siemens SIMATIC Unified Comfort (MTP700 to MTP2200): Powered by HTML5 web technology, multi-touch glass front, and edge runtime application execution in TIA Portal Unified.
Parameter Pro-face GP4000 Series Siemens SIMATIC Unified Comfort
Screen Technology Analog resistive single-touch Capacitive multitouch (Glass front)
Display Sizes 3.5" to 12.1" TFT (65,536 colors) 7.0" to 21.5" Widescreen (16M colors)
Operating System Dedicated Pro-face Real-Time OS Industrial Linux with Siemens Edge Runtime
Connectivity Dual Serial (RS-232/422/485) + Ethernet Dual Gigabit Ethernet (Separate Subnets)

2. Panel Cutout Dimensions & Retrofit Adapter Frames

When replacing an older 10.4" HMI cutout:

  • Use CNC laser-cut aluminum adapter bevel plates to adapt larger panel cutouts without modifying control cabinet sheet metal.
  • Ensure IP65/IP66 front gasket sealing to prevent coolant mist and airborne particulates from contaminating enclosure electronics.

3. Sourcing Touch Glass & Replacement Panels

Touch screen glass delamination, backlight inverter failure, and cracked digitizers require immediate part sourcing.
