Integrating a PLC in End-to-End Tests
For a real end-to-end test in the area of factory automation, robotic or machine tests, you will usually need to access to a PLC (or its HMI), for example to verify that displayed values are correct or if a triggered action has actually been executed. In addition, you may have to simulate the external world or the behavior of other components (eg. sensors).
You can order ready to use libraries from eXept to communicate via OPC-UA, Siemens S7 and others. However, it is also relatively easy to create you own such library. A prerequisite for that is the availability of a library/framework as Java-jar, .NET-Assembly, C/C++, Python- or Node module or in an other of the programming languages which are supported by expecco.
The following describes access via OPC-UA and direct access to a Siemens S7 system.
