A simple HMI application with S7. Net features that you are familiar with. Net, roadmap for future upgrades: Documentation on the driver and S7 protocol The documentation of S7.
Net exposes a class called Plc that contains all the methods that we can use to communicate with the plc: Unfortunately this is quite a messy concept, because usually drivers throws exceptions in case of errors, or returns a value indicating the error and put the requested values inside a memory area passing a pointer to that area.
Here there is the documentation of the protocol, in german: Getting started with S7. Net This paragraph explains how to get S7. Net driver and all the steps from compile the driver to add it into your application.
You can choose to add download it from NuGet fastest way or to include the full sources in your project. The steps to download from NuGet are: Net in the online tab, then install it.
These steps are to include the sources in your application: Net project folder in the folder that contain your project 3 Add the S7. Net project to the solution 4 Add the references A simple application with S7. Also how to write data to the PLC. The application contains 2 projects, one is a wrapper for the plc driver, the other one is a project that contains all the graphic pages.
You can download the sample application on GitHub: Creating a wrapper of S7. Also I just use the highest level features of the driver, and handle all the complexity inside the wrapper.
I use the concept of Tags inside my wrapper, where a Tag is an object containing an address and a value. This is familiar if you already used OPC Servers and Clients, but here it is much more simple and basic. Creation of PLC class inside the main project In the main project I usually define the class that contains the PLC values and communication thread in a singleton.
You can read more about it in this article: The class exposes the properties and methods that are used in all application to communicate with the PLC: The timer callback is responsible to refresh the tags and to calculate the time passed after every read. You can of course use multiple timers, with different Interval value, to better manage the network resources.
DwordVariable, dwordVar ; You can read an example of write and read in the handlers of the MainWindow page. You can also download the sample application for plc created with Step7 5.Windows SIM was unable to generate a catalog.

Note: Maximum interface width varies from device to device depending on the number of I/O pins and DQS or DQ groups available. Achievable interface width also depends on the number of address and command pins that the design requires.
To ensure adequate PLL, clock, and device routing resources are available, you should always test fit any IP in the Quartus ® Prime software before PCB sign-off.
Hello. If your PLC (or another modbus device) is a master, so your PC application will be a slave. In this case the PLC(master) can share is information when ready .
