Example 2

This example is to demonstrate the communication process when diagnose
telegrams and acyclic services are being made use of. A complete and effective error
evaluation will not be made here; in this example, only the basic principle of error
evaluation is to be illustrated.

TASK tInit

;wait, until Init is finished

BIT_CLEAR (rPB_Status, 13)

THEN
