Open Discussion / Driver Siemens with Snap7

« on: November 08, 2020, 03:45:27 PM »

Hello, in case someone is interested, I leave a slightly more tested version of a communication driver for Siemens PLCs that uses Snap7.
To integrate it, you have to copy the files in the "AdvancedHMIDrivers" folder, within the project add the SiemensCom.vb file as an existing element, add the Snap7.net.dll file in "References" and finally copy the "snap7.dll" file. in the build folder of the project "AdvancedHMI \ bin \ Debug"

By the way, it works with the Tia Portal simulator via NetToPLCSim.

Cheers...

Support Questions / OmronEthernetFINSCom error EIPTransport.SendData-No Response

« on: September 14, 2019, 06:39:33 AM »

Hello,
Sorry for my English, it is translated by google translator.
I am trying to connect to an Omron cj2m (UDP) PLC but I also perform tests with a simulator on the PC (the same applies to both the simulator and the PLC). The problem is that the driver responds to me with the error EIPTransport.SendData-No Response (-123). Looking at the packages in the Wireshark seems all right, I have only managed to work from a virtual machine with Windows 7 but I do not find it special for it to work. I add packet capture.
