Hi Bernd,
my name is not Ulrich, but I can still let you know why this trace is different: In this case, the parameter type is a different one, so data transfer is different and will therefore be human readable. Please read my previous post in order to understand how to configure the trace level. Tracing the data content in addition is really rarely needed, but when it occurs is flooding the traces. That's why it is not included in level 4, but needs to be added with the additional trace marker ParameterData. Thus, however, it is even possible to add it when not tracing a lot of other things.
Best regards,
Markus
