As extra suggestion on the guide I could add something if you use Gradle for your software: the compilation build and install all the jars local in your machine, if you would access this local jar storage via gradle you have just to add mavenLocal() to the list of repositories: repositories { mavenCentral() mavenLocal() } I’s not not difficult to figure out but I spend a couple of hours wandering how to do so it’s worth sharing Regards, S.

This is my first project using the S7 protocol and plc4x. When I try to read a value the read request is not being executed (I also do not receive an error message or timeout). Would this be the normal behaviour when the field address is wrong? I’m out of ideas how to trace this down.
