Migrating Legacy HMI Projects: From OP and MP Panels to Newer Siemens Hardware

Planning the replacement of old operator panels without rewriting every screen.

Operator panels from the OP, TP and MP series often outlive the people who programmed them. When one fails, you can either find an identical spare or move to newer hardware.

Option 1: Like-for-like replacement

Quickest and lowest risk. Match the order number and restore the saved project to the panel.

Option 2: Upgrade to a newer family

Siemens provides migration paths from older engineering tools to TIA Portal, but screens, scripts and communication settings still need checking after conversion.

Before you decide

  1. Find the original project file and engineering software version.
  2. Photograph the panel, rear connections and rating plate.
  3. Confirm the controller connection: PROFIBUS, MPI or PROFINET.
  4. Check the available cut-out in the panel door.
