Quick Answer: Siemens vs Mitsubishi HMI — The 30-Second Verdict
Short answer: Siemens is the best HMI brand for plants running SIMATIC S7-1200, S7-1500, S7-200 SMART, or legacy S7-300/S7-200 CPUs, because Comfort Panels and KTP700 integrate natively over Profinet in TIA Portal. Mitsubishi is the better choice for MELSEC FX, Q, or iQ-R lines, where GOT2000 panels deliver dual Ethernet, built-in SD logging, and multi-touch gestures at comparable prices. If you are deciding Siemens or Mitsubishi for HMI purely on PLC family, match the panel to the controller you already own — that single rule eliminates 90% of migration headaches.
For a Siemens HMI comparison against Mitsubishi GOT hardware, the practical split is fieldbus and legacy support. Siemens covers Profinet, MPI, and Profibus across the KTP700, TP177B, and TD200C families, while Mitsubishi covers RS-232/422/485 plus Ethernet across GOT1000, GOT2000, and A900GOT. Both brands remain fully buyable today, including discontinued models, so the decision usually comes down to your existing PLC platform rather than availability.

Programming & Integration Differences: Siemens HMI vs Mitsubishi GOT
Siemens HMIs are engineered inside TIA Portal using SIMATIC WinCC Basic, Comfort, or Advanced, depending on panel class. Comfort Panels such as the TP700 through TP2200 are native Profinet devices, which makes them drop-in replacements on S7-1200 and S7-1500 controllers. Legacy panels extend backward: the TP177B speaks MPI and Profibus, while the TD200C pairs directly with S7-200 CPUs. In practice, an 6ES7 288-1ST20-0AA0 - S7-200 SMART CPU ST20 or 6ES7 216-2AD23-0XB0 - CPU 226 pairs naturally with a KTP700 or TD200C, and a CPU 314C-2 PN/DP (6ES7 314-6EH04-0AB0) sits comfortably behind any Comfort Panel.
Mitsubishi programs its HMIs in GT Designer3, covering both GOT2000 and GOT1000. The GOT2000 series — GT2705, GT2708, GT2710, GT2712, GT2715 — adds dual Ethernet, SD card logging, multi-touch gestures, and gateway functions that let a GOT panel bridge MELSEC controllers to third-party PLCs. Typical partners include the FX3U-64MR/ES-A - MELSEC FX3U-64MR and larger Q/iQ-R racks. When migrating between brands, expect differences in fieldbus (Profinet vs CC-Link IE Field/Ethernet), tag import workflow, screen conversion tooling, licensing cost, and cable/connector pinouts. Planning those four items up front is what separates a clean Siemens HMI comparison from a stalled retrofit.
Which Should You Choose? Decision Guide (Siemens or Mitsubishi for HMI)
Choose Siemens HMI when your plant standardizes on SIMATIC S7-1200, S7-1500, S7-200 SMART, or legacy S7-300/S7-200 hardware, when a single TIA Portal engineering environment matters, or when you need IP65 washdown panels and widescreen Comfort displays from 7" to 22" (TP700 through TP2200). The KTP700 is the natural entry point for S7-200 SMART and S7-1200 lines, while the TP2200 at 1920×1080 suits control-room dashboards. Browse the Siemens HMI inventory to match panel size to your controller.
Choose Mitsubishi HMI when you already run MELSEC FX3U, Q, or iQ-R infrastructure, when you need a GOT1000 GT1055 or GT15 drop-in replacement, or when you want dual Ethernet, SD data logging, and multi-touch gestures on a GOT2000 panel. A budget 5.7"–15" panel at $500–1,500 is realistic across the GT2705 to GT2715 range. Before you buy, run this checklist: PLC family, fieldbus (Profinet vs MELSEC Ethernet/CC-Link), screen size, legacy support window, spare-part availability, and total cost of ownership across five years. The same checklist works whether you buy Siemens HMI or buy Mitsubishi GOT — see the Mitsubishi GOT inventory for current stock.
Frequently Asked Questions: Siemens vs Mitsubishi HMI
Is Siemens or Mitsubishi better for HMI in a factory running MELSEC PLCs?
Mitsubishi is the better fit for MELSEC plants. GOT2000 panels like the GT2705-VTBD and GT2710-VTBD connect natively to FX, Q, and iQ-R controllers over Ethernet, while Siemens panels would require protocol gateways. In stock at zzsl-pcl.com from $500–2,000.
Can I replace a Mitsubishi GOT1000 GT1055 with a GOT2000 GT2705?
Yes, in most cases. GT Designer3 supports screen conversion from GOT1000 to GOT2000, and the GT2705-VTBD offers 640×480 resolution versus the GT1055-QSBD at 320×240. Confirm connector and mounting dimensions before ordering; the GT2705-VTBD is in stock at $500–800.
What is the price of a Siemens KTP700 vs a Mitsubishi GT2705?
The Siemens KTP700 (6ES7647-0AA00-0AX2) is ¥3,500–4,500, while the Mitsubishi GT2705-VTBD is $500–800. Both are in stock now. Final pricing depends on quantity and shipping destination — request a quote for bulk orders.
Are Siemens TP177B and Mitsubishi A960GOT still available as replacements?
Yes, both legacy panels remain sourceable. The Siemens TP177B 6" (6AV6640-0DA00-0AX1) is ¥4,500–5,500 and the Mitsubishi A960GOT-TBD is ¥2,200–2,800, both in limited stock. Contact us for verified availability before committing to a retrofit schedule.
Which HMI brand is easier to program — WinCC/TIA Portal or GT Designer3?
TIA Portal WinCC is easier if your plant already uses Siemens PLCs, since tags, alarms, and screens share one project. GT Designer3 is faster for MELSEC users because it auto-imports FX/Q/iQ-R device tags. Both are mature tools — the deciding factor is your PLC family. Browse both brands at zzsl-pcl.com.
