29th June 2022 (Europe 1)


We have worked hard to deliver a great MindSphere experience. These release notes are relevant for MindSphere Release by June 2022 and include new and adjusted features or fixed issues. If you find other issues, please give us your feedback by contacting our MindSphere Support.

MindSphere Remote Service

Applicable for

  • MindAccess IoT Value Plan
  • MindSphere Packaging and Pricing

What's new?

  • The technical term of downloadable clients is being replaced by a usage-related term, so they become endpoints. Thus, "Operator Client" is now referred as "Service Endpoint" and "Device Client" is now referred as "Device Endpoint".
  • Protocol Applications may now be assigned with custom idle timeouts. Protocol Applications will be closed automatically upon idle timeout expiration - so "Service Tunnels" will be freed automatically.
  • Tunnel connections can now be activated and terminated in MRS UI V2.
  • The Protocol Hub used for creating new Protocol Applications now tags all protocol tiles with the name of MRS upgrade packages, if purchased.
  • Improved billing of MRS resources in legacy IOT value plan deployments.
  • Audit and system logs were enhanced by an export capability.
  • Columns in audit log view can be resized easily.
  • Names of files transferred via MRS UI are now subject to audit log.


Most functional extensions of MindSphere Remote Service become available only under new MindSphere packaging and pricing. So please, reach out to your Sales representative to have your subscription of IOT value plan upgraded accordingly.

System Requirements for MindSphere Remote Service (MRS)

Browser-based access to MindSphere Remote Services App on MindSphere

  • Microsoft WindowsTM 10 version 1909: Google ChromeTM (version 68 or newer)
  • recommended screen resolution: 1280x1024 and 1920x1080 with zoom level 100%

Requirements for service personnel's PCs hosting MRS Service Endpoint (former Operator Client) as entry point for network-to-network access

  • Service Endpoint (Operator Client) can be downloaded from MRS
  • Validated Hardware

    • Processor: 32-bit or x64-based (Intel or AMD)
    • Display size / resolution: 1280x1024 and 1920x1080 with zoom level 100%*
    • Disk space occupied by Operator Client: 32MB
  • Validated Operating Systems and Browsers

  • Microsoft Windows ® 10 Version 1909
  • Linux ® Debian 9
  • Linux ® RedHat 7.6
  • Google Chrome TM version 68 or newer

Requirements for accessed devices hosting MRS Device Endpoint (former Device Client) as end point for network-to-network access

  • Device Endpoint (Device Client) can be downloaded from MRS
  • Validated Hardware

    • Processor: 32-bit or x64-based (Intel or AMD)
    • RAM: 0.5GB
    • disk space occupied by Device Client: 32MB
  • Validated Operating Systems

    • Microsoft Windows ® 10 Version 1909
    • Linux ® Debian 9
    • Linux ® RedHat 7.6

Requirements for transmitting application protocols with Remote Service

  • Operating system of Operator PC must provide clients for the used outgoing Remote Login protocols (e.g. RDP, VNC), whilst Engineering Tools used remotely on Operator PC typically have built-in clients for such protocols
  • Operating system of Serviced Assets must provide servers for the incoming Remote Login protocols (e.g. RDP, VNC, SSH) or for the incoming Remote Engineering protocols
  • Native Remote Desktop Protocol (RDP) can only be launched from Windows ® based Operator PCs supporting this Remote Login protocol
  • The download package of the Operator Client contains a Windows driver (installer file MRSTransparentProxy.msi) for Proxy-Unaware protocol
  • Remote Engineering via Proxy-Unaware protocol is only available on WindowsTM based Operator PCs

Known issues

  • There is no auto-assignment of RDP (and Ping) to secondary Service Assets. These must be assigned manually via MRS Protocol Applications.
  • Service Assets may be serviced without upfront registration by means of On-Demand Devices. Such On-Demand Devices have an expiration date, and they will show up in the MRS asset tree until then. The expiration date is not enforced, so manual de-registration is necessary.
  • Connectivity status of secondary Service Assets behind a gateway might not be shown as "connected", even though the secondary Service Asset can be accessed.
  • Configuration changes are tracked in audit trail and system logs. Selected changes could be also be propagated via email notifications, which are not available for connection establishment or file transfers.
  • It is recommended to have "Red Button" deactivated when working on the related Service Asset to ensure its proper setup.
