Enabling traces in the ISO8583 Payments Simulator, just like the ISO8583 message converter and the ISO8583 Host, is a call to the system core to write additional data.

Most importantly, enabling traces shows dumps of TCP traffic or actual data being written to files, queries do database and so on. This is to verify that you are sending the correct data.
