   I cannot read REAL values from a S7-1500 with PLC4J with version 0.10.0.
   
   I get the following error from the PLC4J Lib:
   
   ```bash
   Caused by: java.lang.NullPointerException: Cannot invoke 
"org.apache.plc4x.java.s7.readwrite.S7PayloadReadVarResponse.getItems()" 
because "payload" is null
   ```
