Requirements and installation

The additional requirements and necessary installation steps for the S7 Plus driver.

Requirements

  • Installed WinCC OA version
  • A valid S7Plus license (depending on the acquired license up to 8, 64 or 512 connections are available; for more information regarding calculation of connections refer to Licensing and FAQ - S7 Plus Driver).

Please note that it is NOT possible to combine two licenses, e.g. License A: 64 connections, license B: 64 connections will not provide 128 connections in total, but only the 64 connections the active license provides.

  • Following S7 PLCs are supported:
    • S7-1200
    • S7-1500 & S7-1500R/H
    • S7-1500 Software Controller
    • ET200SP
Important:
Due to the absence of a TCP connection during the SYNCUP phase of the S7-1500R/H system, values cannot be written during this interval.

TSPP

Following additional requirements must be considered when using the "Receive Mode" TSPP:

  • Only S7-1500 PLCs with a firmware version 2.6 and newer are supported.

TIA Portal

All TIA Portal versions >= V13.1 are supported but necessary export plug-ins must be downloaded from SIMATIC SCADA Export for TIA Portal (SiePortal).

If Offline browsing is used, all TIA projects used by the driver must be available as a TIA export. file at runtime. Therefore the projects must be exported via the TIA portal's export tool.

The export tool is stored under <wincc_oa_path>/data/clsetup after installing the S7Plus component.

If required, install the appropriate tool for your TIA Portal version and then start the TIA portal. Right-click on the project or a PLC and select the Export to SIMATIC SCADA from the context menu.

The exported project must be stored under <WinCC_OA_Proj>/data/TIA_Projects on the host where the driver is running. This also applies to the redundant driver in case of a redundant project.

Note:
TIA export files larger than 128 MB cannot be used and result in the following error message: WCCOAs7plus (1), 2017.06.12 12:04:29.134, SYS,SEVERE, 54, Unexpected state, Error in decoding TIA Project <project name>, too large document

For information on supported platforms for the S7Plus driver refer to the chapter Drivers - Supported Platforms of the main Drivers.

Restriction:
Please note that a TLS connection can only be used with TIA Portal V17 and S7-1500 firmware V2.9 and S7-1200 V4.5 and later
Restriction:
Please note, that combining the TIA Importer and Mass configuration is not supported as it will lead to inconsistent configuration results.

Installation

To use the S7Plus driver, select the menu item S7Plus driver during the installation of WinCC OA.In this case the Siemens S7DOS component is automatically installed. You have to restart the computer after the S7DOS installation.

Note:
The S7DOS component cannot be uninstalled by using the WinCC OA setup.
Note:
The Repair option of the WinCC OAsetup is not supported for the S7Plus driver. In the event of a setup error in the driver or S7DOS, you must therefore completely uninstall and reinstall WinCC OA.

Refer to the installation chapter for further information on installing WinCC OA.
