While keeping the NT Series Support Tool on hand is vital for immediate maintenance, planning for hardware lifecycle exhaustion is a priority. Omron officially recommends migrating aging NT-series touchscreens to their modern or NA Series smart HMIs. The software configurations built inside legacy NTST can often be imported, converted, and upscaled using Omron's modern Sysmac Studio or NB-Designer software, minimizing engineering downtime during physical hardware upgrades.
The is the legacy software package used for creating and maintaining screen data for Omron Programmable Terminals (HMIs) . While much of Omron's current HMI development has shifted to modern suites like CX-One or Sysmac Studio , the NTST remains essential for maintaining older hardware like the NT20, NT31, and NT631 series .
