Before installing or upgrading Web HMI, verify the following software is installed on your system.

Note: Run Windows Update (including security updates) before installing or upgrading Web HMI.
  • .NET Framework 3.5
  • GE Historian Client tools (if using Historical data):
    • Historian 7.0 SP5 (for Historian 7.0)
    • Historian 7.0 SP1 (for Historian 7.0)
    • Historian 6.0 SP1 SIM 5 (for Historian 6.0)
    • Historian 5.5 SIM 29 (for Historian 5.5)


Important: If using iFIX for your HMI/SCADA system, it is strongly recommended that you install it before installing Web HMI. If you do not, you must start the Data Service Configuration tool after installing iFIX, as explained in Run the Data Service Configuration Tool.

Web HMI works with iFIX 5.9 or 5.8. If installing iFIX 5.8 on your system (HMI/SCADA or View Node, as required), install its software in this order:

  • GE iFIX 5.8
  • GE iFIX 5.8 SP2
  • GE iFIX58_HPDynamos_001
  • GE iFIX58_ExportJSON_002
  • GE iFIX58_Blocks_001
