RK512 Communication

The example program defines three WORD arrays, in order to use them as data blocks. During initialisation the data blocks 5 and 10 are registered for access by the communication partners by calling the DBconfig method. The function block RK512 behaves passively, and is ready to accept and to answer data telegrams from the partner device. The test program allows active sending or fetching of data to be initiated by writing to the Send or Fetch variables.
