SI-Apps Compact Module
  • Overview

SI-Apps Compact modules allow SyPTPro application programs to be recompiled and executed with Digitax HD or Unidrive M700 to enable rapid and simple upgrade for Unidrive SP users.

Applications comprising of networked Unidrive SP drives with SM-Applications using CTNet or CTSync for real-time control can be quickly replaced with Digitax HD or Unidrive M700 and the SI-Apps Compact module without any compromise to system performance.
