Siemens S7 driver

[aqwsderf]

Hi All
I'm looking for Siemens S7 driver for communication with 1200/1500 CPU in a similar way as for AB CLX. I've found many old topics related to such kind of driver (https://www.advancedhmi.com/forum/index.php?topic=2605.0 for example), but I've not found binaries or sources here.

Could anyone help me sort out with it issue?

Thanks in advance!

I use the attached driver with great success in my plant with over 50 S7-300 PLCs, So far only for machine interface and data acquisition but it seems very stable. I have not tested with a 1200 yet but I will be soon and post my findings.

I see this driver is a wrapper for the Snap7 driver. Looks like a good job was done on the wrapper code. For anyone wanting to try this Siemens driver, here are the steps:

- Download and extract the 3 files
- Open the AdvancedHMI solution in VS
- In Solution Explorer expand down the AdvancedHMDrivers project
- Right click the Support folder and select Add Existing Items
- Browse to the 3 extracted files
- Change the file type filter to All Files
- Select the 2 DLL files
- With the 2 DLL files now in the Support folder, select each one by clicking once on it, then in the Properties set "Copy if Newer"

- Right click the AdvancedHMIDrivers project and Select Add Existing Item
- Browse to and select the SiemensCom.vb file

- Right click the AdvancedHMIDrivers project and Select Add References
- Browse to and select Snap7.net.dll

I think following Archie's steps is the easiest way. Any chance you can show us your way if that is possible.

I can confirm the driver is very stable on the S7-1200 PLCs, I will be on the 1500s next.

This is awesome, nice work to everyone responsible. Does anyone know what the format for setting the plc tag address would be? Is non-optimized data blocks required? Any place to find further documentation? Hopefully this is a new add in the next version of AdvancedHMI
