The Omron NT-Series Support Tool (NTST) is the legacy software used to design, edit, and maintain screen data for Omron’s NT-Series HMI (Human Machine Interface) terminals, such as the NT21, NT31, and NT631. While newer HMI series like the NS-Series have succeeded it, NTST remains essential for maintaining older automation systems. Official Download Channels
This absence has forced the automation community into alternative channels. Engineers often find themselves scouring third-party automation forums, abandoned FTP archives, or legacy industrial software repositories. The software typically circulates under specific version numbers, such as "NTST Ver 4.8," which was one of the final releases capable of supporting the entire NT family.
Warning: Downloading NTST from torrent sites or unverified file repositories is extremely risky. Industrial PCs running automation software are often mission-critical. Ransomware or viruses from a cracked installer could halt production.
