Combined configuration with WinCC (TIA Portal) and STEP 7 V5.x or Combined configuration with WinCC (TIA Portal) and STEP 7 (TIA Portel) in separate projects (Video)

  • Entry
  • Associated product(s)
By means of the “device proxy PLC”, you can directly access the SIMATIC controllers configured in the SIMATIC Manager and their current data such as symbols, data blocks and the alarm procedures “Alarm_S”, “Alarm_D” and “SFM”. Or you can work with WinCC (TIA Portal) and STEP 7 (TIA Portal) in separate projects. GSDML files are available for download ("Direct button” function).

The TIA Portal offers the option to create the PLC programs and HMI configurations via a uniform software interface.
In some cases it is necessary, due to technical or customer-specific reasons, to continue creating the PLC program with the “STEP 7 V5.x” software and the HMI configuration with the “WinCC (TIA Portal)” software.

If tags are newly created or processed in the STEP 7 program for the data exchange for the HMI operator panel, these changes should also be made in the HMI project without great effort. In order to avoid address and spelling mistakes, no manual adjustment of the address or tag name should be made in the HMI project.

Video - SIMATIC WinCC V13
Through the “Device Proxy PLC” you can directly access the SIMATIC controllers configured in the SIMATIC Manager and their current data such as symbolism, data blocks and the alarm procedure “Alarm_S”, “Alarm_D” and “SFM”.

There are several options to implement the task.

  • The “Device Proxy PLC” enables directly accessing the SIMATIC controllers and their current data such as symbols, data blocks and the “Alarm_S”, “Alarm_D” and “SFM” alarm procedure in the SIMATIC Manager and integrating it into WinCC (TIA Portal).
    The handling can be compared with a WinCC flexible project integrated in the SIMATIC Manager.

Note on PCS 7 CPU 410-5H
You can only select the CPU 410-5H as the source for a proxy CPU if there is also a corresponding PCS 7 installation on your WinCC (TIA Portal) configuration computer.

WinCC (TIA Portal) and STEP 7 (TIA Portal) in separate projects
You can also use STEP 7 (TIA Portal) configurations in a separate project using the "Devices Proxy-PLC" function. This allows to separate into two projects, WinCC (TIA Portal) and STEP 7 (TIA Portal). For example, an HMI developer and an S7 programmer can simultaneously work on a job in two (by proxy PLC) "connected" projects.

WinAC RTX (F) (STEP 7 V5.x) with WinCC Runtime (TIA Portal) on a PC Station
Apart from the pure hardware controllers the WinAC RTX (F) software controller can also be configured in STEP 7 V5.x and be operated using WinCC Runtime Advanced or WinCC Runtime Professional.

WinAC RTX (F) as well as WinCC Runtime (TIA Portal) can be located on the same PC station. The following documentation shows you how to operate WinAC RTX (F) from STEP 7 V5.x and WinCC Runtime from the TIA Portal on a PC Station.
