Download and sales/delivery release for SINEMA Remote Connect V3.0 SP2

  • Entry
  • Associated product(s)
V3.0 SP2 of SINEMA Remote Connect is hereby released. The upgrade for the server to V3.0 SP2 is free of charge; please refer to the installation instructions. One-off, low migration costs will be incurred for the client update V3.0.

The following is offered for download:

  • Upgrade installation file for SINEMA Remote Connect Server V3.0 SP2
  • Installation files for SINEMA Remote Connect Client V3.0 SP1
    (including UMC server installation)
  • Optional: VMware Tools V3.0 for installation via update routine
  • Optional: OSS packages used

SINEMA Remote Connect, the management platform for remote networks, is a server application for establishing secure connections between users, widely distributed plants and machines. SINEMA Remote Connect enables management and establishment of tunnel connections (VPN).

V3.0 of SINEMA Remote Connect provides the option to install the SINEMA Remote Connect Server in a cloud environment for the first time. Amazon Web Services and Microsoft Azure are released and tested cloud systems. 

With this version, it is also possible to enable a REST-API (automation interface), which can provide significantly increased productivity through automation. This means that relevant configurations (e.g. adding devices/groups, enabling/disabling users, setting up servers, configuring parameters) can now easily and efficiently be performed automatically instead of manually if required. You can develop your own corresponding scripts/programs for this. The REST-API (must be purchased separately with a license) also allows a flow of information from SINEMA Remote Connect into your own systems, e.g. to enable monitoring (e.g. integrating data from SINEMA Remote Connect into your own statistics/dashboards). To use the API interface, please note that a one-time additional license is required in the SINEMA RC server (SINEMA RC API license - 6GK1724-3VH03-0BV0). For test purposes, a one-time 14-day trial version can be activated. 

The SINEMA Remote Connect Client license via the Automation License Manager is replaced by a new central client license which is imported into the SINEMA Remote Connect Server and managed there. The license model, whereby each PC connected to the server on which the SINEMA Remote Connect Client is licensed, has not changed. Only the location of license management has changed. As soon as a SINEMA Remote Connect Client connects to the server, a client license is occupied for this client on the server. Please ensure that there is a sufficient number of available client licenses on the server. If the new SINEMA Remote Connect Client is installed on the same host in multiple virtual machines, only one license is occupied in total for the virtual machines. Please note that a license migration is necessary before the server update. This is explained in greater detail in the migration process under "Item 3. Download". 

For the first time, an Online Software Delivery is also offered within the SINEMA Remote Connect portfolio. Online Software Delivery (OSD) offers you direct, convenient downloading of your purchased software and the corresponding license keys. 


Security information:

Version 3.0 contains safety-relevant changes which enhance robustness against possible attacks. Updating to version 3.0 is therefore recommended.

For optimum interoperability, it is always advisable to upgrade both the SINEMA Remote Connect Server and the SINEMA Remote Connect Client to the latest version.

    2. Ordering data

    When ordering the SINEMA Remote Connect Client Software V3 (6GK1721-1XG03-0AA0 / 6GK1721-1XG03-0AK0 / 6GK1721-3XG03-0AK0), note that the licenses are bundled for each order. This has the advantage that any quantity of the SINEMA Remote Connect Client V3 can be ordered, but you receive only one package with the software/OSD download and a license key that corresponds exactly to the ordered quantity and needs to be activated in the server.

    3. Download

    Caution! Before you upgrade the server to V3.0, you need to migrate the client licenses. To run though this migration, please order the SINEMA RC CLIENT V3 Upgrade (OSD) license (6GK1721-3XG03-0AK0) in the same quantity as the SINEMA Remote Connect Client licenses (6GK1721-1XG01-0AA0) that you possess.

    Please note that the SINEMA Remote Connect Virtual Appliance (6GK1720-1AH01-0BV0) also contains a SINEMA RC Client, which is entitled to an upgrade. Scaled prices which result in a one-off, low migration fee are available for the upgrade order number. The release of your new licenses is then sent to you by download and needs to be activated once on the SINEMA Remote Connect Server V3.0. If you did not do this before the server update, you have 30 days to activate the client licenses retroactively.

    Updating the server:

    The description of the system update can be found in the operating instructions for SINEMA Remote Connect:  https://support.industry.siemens.com/cs/attachments/109482121/BA_SINEMA-RC-Server_0.pdf?

    It is only possible to update to version 3.0 SP2 from V2.1 or V3.0/V3.0 SP1; please observe the corresponding information in the manual.

    Version 3.0 SP2 is loaded via the server's Web-based Management. Please ensure that your system (including documentation of all network settings) has been backed up and follow the instructions in the manual.

    Note: Depending on the hardware, installation of the update can take up to 60 minutes.  The SINEMA Remote Connect Server restarts during the update and is temporarily unavailable. While the update is in progress, the system must not be disconnected from the power supply system or restarted because this will interrupt the update and possibly impair the installation. The update has been successfully completed when the SINEMA Remote Connect Server has booted on its own and the Web-based Management is accessible again. It is possible that the update display in the browser will not be updated. Therefore, it is recommended that you open the website again to check whether the update was successful. After login to the Web-based Management, V3.0.2.0 should be shown under "System" à "Overview" à "Software version".


    Installation of the client:

    The update to Version 3.0 SP1 can be performed from any client version. Please observe the relevant information in the manual.

    The current Windows updates are a prerequisite for installing the SINEMA Remote Connect Client.

    Check whether your operating system is up to date before installing the SINEMA Remote Connect Client.


    Compatibility of server and client versions

    As described in the manual, we strongly recommend updating the server and client. However, in the transitional phase, it is also technically possible to use the following combinations with limited functional scope:

    SINEMA Remote Connect Server V3.0 SP2 with SINEMA Remote Connect Client V2.1

    SINEMA Remote Connect Server V2.1 with SINEMA Remote Connect Client V3.0 SP1
