Since years, there are tons of driver/connector in both commercial and open source that support connect to S7 family PLC devices. GoS7 is just simple missing pieces in S7 protocol which implementing in with pure Go(aka golang) with a strongly faith that low-level communication would be impelement. Release 2.0.0 (February 8th, 2015): Changes: This release adds options to configure the rack and slot number for the PLC connection, thus enabling communication with a wider range of S7 PLCs. It also changes the way that individual bits in DB areas are addressed, so that the address format now matches the format used by most S7 tools. Yeah, I also tought it would be slot 0, but it looks like something is missing in the Libnodave, because on a S7-300 it works. Regards, C Am in the midst of panel construction, but will hopefully get a bit of time later. For the S7-1200 I think it should be Rack 0, Slot 1.

Hi I am using the S7.net library in C# in order to read data from a VIPA PLC (similar to S7-300). The C# project runs on a virtual machine (Windows 10 Pro, 64 bit) and is programmed in Visual Studio 2019.
Nfl slot receivers 2021. I have a weird problem with my Connection from C# to my Simatic S7-1200.I am using LibNoDave to connect and i want to set bits of my SPS with the C#-program.This is working just fine but it only works 9 times and then the writeBytes(.) function returns -1025 and not 0 as it should and it is not setting the byte anymore.I then have to restart the application and it will work 9 times again.
This is my LibNoDave class.
Here I am calling the functions:

I don´t see any problem in code and I don´t know neither your device nor LibNoDave, but the problem may be related to:

I don´t see any problem in code and I don´t know neither your device nor LibNoDave, but the problem may be related to:
1- Is some receiver an 'One single digit' (like 0 to 9) address or container ?
2- The position is being truly reseted as I see in WritePLC function?
3- The 'LibNoDave.WritePLC' is incrementing its pointer?
Good luck.
Just a wild shot, but is the libnodave.dll a native DLL and libnodave.net.dll a wrapper for this DLL? Then you need to make sure that Libnodave is a free library compiled in some programming languages (C, C++, C# etc) that permit to exchange data with Siemens PLC for free and to embed the driver in the program. You just have to add as reference the libnodave.Net.dll and start to read and write data using the simple samples inside the docs. The main page of libnodave is here:

It's old, but for others to find: in my case it was the declaration of fds and di: they had to be class members and not local to the connect method, or the timeout value was being lost later on.
