VTScada PC Recommendations

For VTScada Licenses Installed On Windows® Operating Systems

 Small Systems
Less than 1K I/O

  • 32- or 64-bit Windows OS.
  • 2 GHz dual-core processor.
  • 40 GB free drive space.
  • 4 GB RAM.
  • 100 Mb Ethernet or higher.

Medium Systems
1K to 25K I/O

  • 64-bit Windows OS.
  • 3 GHz or more quad-core processor. Note: High clock speeds are more helpful than more cores.
  • Solid State Drive.
  • 1TB free space.
  • 16 GB RAM.
  • 1 Gb Ethernet or higher.

Large Systems
Over 25K I/O

  • Medium Systems spec (left) should be adequate for +100K systems.
  • Increase processor clock speed to 4 GHz or higher.
  • Scale to large systems by load sharing services across servers or using Master & Subordinate Apps.
  • If using blade servers, high clock speeds help, more cores don’t.
  • Use segmented networks.

Compatible Operating Systems by VTScada Version

VTScada OS Compatibility

Note: VTScada runs on Windows® 10 IoT Enterprise not IoT Core. Microsoft has ended support for Windows 7®, Server 2008 R2®, Windows 8®, Windows Vista®, Windows XP®, and Server 2008®.

Alarm
Notifications

  • Text-to-speech phone alerts require a voice modem or web-based messaging service like Twilio®.
  • See the VTScada Users Forum for help choosing modems.
  • Connection to an email server required for email alarm notifications.
  • Cell modem or email account required for text alarm notifications.
  • Sound card and speakers required for local alarm annunciation.

Virtualized
Servers

  • VTScada can run on virtual Servers.
  • Don’t clone virtual servers with VTScada installed. To learn more, search ‘virtual servers’ in VTScada Help.
  • Ensure host PCs have enough capacity for all VMs, e.g., CPU, RAM, drive space, ports, Ethernet bandwidth.
  • Twilio (left) offers a simple alternative to configuring voice modems in virtual server environments.

Other
Recommendations

  • If you need RS-232 ports to communicate with legacy devices, we recommend Ethernet to serial converters.
  • Keep VTScada & History data on separate drive from OS.
  • NetDDE is not available on Vista and higher (removed in XP Service Pack II).
  • VTScada uses IANA registered TCP/IP port 5780. Set up firewalls to route RPC traffic accordingly.
  • Configure RAID with standard or solid-state drives. SSDs provides better performance.
