Hello,
I would like to know if it is possible to include a library like EasyModbusTCP in a FunctionBlock to use it in PLCNextEngineer (yes I know there is a ModbusTCP library made by Phoenix Contact)? I tried it but was not able to execute any of the FunctionBlocks that I imported in my PLCNextEnginner Project.
I would like to know if it is possible to include a library like EasyModbusTCP in a FunctionBlock to use it in PLCNextEngineerNo, that’s not possible.
Code that targets the Embedded Common Language Runtime (eCLR) can only use the classes that are provided with the eCLR. The complete list of available eCLR classes is shown in the documentation when you create a new PLCnext C# project in Visual Studio.
You could write a C# application that targets .NET Core, like these three examples demonstrate:
Install the .NET Core runtime 3.0.0 on the AXC F 2152 - PLCnext Community Abstract This guide explains how to install the dotnet core runtime version 3.0.0 on the PLCnext controller AXC F 2152. The controller need at least the firmware 2019.6.3 installed. Installation Download the dotnet runtime binaries for Linux ARM32. Copy the archive to the controller. Connect with ssh to the controller and open a root login shell. […] Getting started with C# and .Net Core 3.0 on PLCnext - PLCnext Community The following post shows a workflow how to develop a .Net Core application for a PLCnext target.It is containing two steps: Create a Hello World application with VS Code. Publish the application to the controller. In this example I’m using Debian 9 on my development machine and an AXC F 2152 with version: PLCnext Linux […] How to create a simple PLCnext console application in C# - PLCnext Community PLCnext Technology from Phoenix Contact is a unique, open ecosystem for modern automation that is capable of meeting all the challenges of the IoT world. … but these applications do not have a tight integration with PLCnext Engineer, so you would need to exchange data with the PLCnext Engineer project via Global Data Space (GDS) variables using (for example) gRPC, REST or OPC UA.
In case it helps, according to the PLCnext Runtime System roadmap, an integrated Modbus/TCP client should be available in an upcoming PLCnext Engineer release, which will be handier to use than the Modbus/TCP library for many cases.
