Writeable addresses:
- Networkinputs, analog network inputs
- Output, analog output
- Network output and analog network output
- Flag (bit memory), analog flag
- V-area
See in this video how to use ComDrvS7 with Visual Studio 2010.
A small "Windows Form Application" in C# will be created and you see how you can access a S7-300 PLC over TCP/IP.
Can be used with the following operating systems:
- Windows 10 (32- and 64 Bit)
- Windows 8 (32- and 64 Bit)
- Windows 7 (32- and 64 Bit)
- Windows XP (32 Bit)
- Windows Vista (32- and 64 Bit)
- For all Editions: Home, Pro, Ultimate
Note:
Your application must be a 32-Bit-Software.
If your application is a native 64 Bit Software you need "ComDrvS7 Developer License" and "ComDrvS7 64 Bit Option for the Developer License"
