Known issues experienced when using Windows "Remote Desktop"

[Product_Support]

Issue

Users may encounter unexpected behavior when accessing certain applications via Windows Remote Desktop (RDP). These issues may appear to be product-related but are actually due to limitations or behaviors of RDP itself.

Product Line

Satchwell BAS & Sigma

Environment

• Sigma
• ModBMS
• OPC

Cause

These issues stem from how Windows Remote Desktop handles hardware and graphical interfaces. It may not fully support certain device drivers or UI components, leading to inconsistent behavior.

Resolution

 Affected Components and Symptoms

1. Sigma – Dongle Configuration Error

   • Symptom: When the dongle is checked from a remote PC, the configuration appears incorrect.
   • Clarification: On the local server, the dongle is correctly configured. This discrepancy is due to how Remote Desktop interacts with hardware dongles.

2. Sigma – Alarm Manager Operation

   • Symptom: Alarm Manager does not function as expected when accessed remotely.
   • Clarification: The application operates normally when used directly on the server.

3. MatrikonOPC Client

   • Symptom: OPC data is not displayed correctly via Remote Desktop.
   • Workaround: Viewing the client through VNC instead of Remote Desktop resolves the issue.

Recommendations

• Use Local Access: Whenever possible, access affected applications directly from the server.
• Alternative Remote Tools: Consider using VNC or other remote access solutions that better support hardware and graphical interfaces.
• Verify Locally: Always confirm configuration and functionality directly on the server before troubleshooting further.
