When you move Siemens engineering to a vDesktop, you centralize security:
| Control | Implementation |
|---------|----------------|
| No local admin rights | Engineers still need admin for installing GSD files, but use Windows LAPS + just-in-time admin. |
| Network separation | Place vDesktop in an engineering VLAN with access only to PLCs via jump host. |
| Logging | All TIA Portal uploads/downloads logged via Siemens PLCMonitor or SIEM (e.g., Splunk). |
| Backup | Persist vDesktops daily; non-persistent pools capture project data in FSLogix containers. |
Many Siemens plants reject pure cloud vDesktop (latency). Prefer on-prem VMware Horizon or Azure Stack HCI local.
There is no single "Siemens VDI" product. Instead, you run Siemens software on third-party VDI platforms. The most common architectures include: vdesktop siemens
The migration to a Siemens vDesktop is not without friction. Real-time computing remains a hurdle. Virtualized environments introduce latency that is unacceptable for hard real-time control loops (microsecond-level responses). Therefore, vDesktop is typically reserved for the engineering and supervisory (SCADA) layers, not the actual motion control of the servo motor.
Furthermore, graphical performance for heavy CAD (Siemens NX) requires GPU-paravirtualization, which adds cost. Organizations must carefully profile their workloads to decide which users get a shared vDesktop versus a high-end dedicated virtual workstation.
You typically deploy one of three patterns: When you move Siemens engineering to a vDesktop,
The cloud-native approach. Siemens software runs on Azure’s high-compute instances. Best for temporary project teams or disaster recovery sites. Warning: Cloud egress costs for large PLC project files can be high.
Sizing is the most critical step. A standard office VDI cannot run Siemens VDI.
Industrial automation engineering is notoriously resource-hungry. Running TIA Portal, SIMATIC Manager, WinCC, PLCSIM, and NX simultaneously demands high CPU clock speeds, 32+ GB RAM, and fast SSDs. When those environments are deployed on physical workstations, you face: Many Siemens plants reject pure cloud vDesktop (latency)
Enter the vDesktop Siemens – a virtualized Windows engineering workstation hosted on-premises or in the cloud (eg, Azure, AWS Outposts), providing access via PCoIP, Blast, or RDP.
Definition: A Siemens-optimized VDI delivers a fully licensed, persistent or non-persistent engineering desktop, pre-configured with TIA Portal, Step7, WinCC, and hardware connections via USB/IP or network tunneled PROFINET.
A machine builder has programmers in India, Germany, and the USA. By centralizing on a vDesktop Siemens solution, they eliminated code synchronization issues. ROI was achieved in 8 months due to reduced travel and license duplication.
