Description

Use case

Writing CHAR array to S7 PLc via plc4x sink kafka connector was throwing an error, as is shown in the code snippet:

"sinks.CommonPlcSetup.fields.steelGradeCurrent": "%DB851:136:CHAR[12]" 

The error messages

Context

This was working with version 0.9.0-SNAPSHOT, but my customized version could no longer be compiled on 0.9.0-SNAPSHOT, so I had to compile the the code against 0.10.0-SNAPSHOT
