Sequential tracing is used for tracing an activity. Through the

sequential trace, the signals can be followed in their logical and

chronological order and thus the chain of events that led to the fault.

Sequential tracing should be used when the user has an idea of the

activity that went wrong and wants to locate the break in the

sequence.

• Interface tracing

Interface tracing is used to trace all signals to and from a program

unit or a hardware equipment position. This form of tracing is used,

for example, when the unit where the fault occurs is already known

or suspected, but the process that caused the fault is not known (for

example, when a faulty signal in a unit has been received).

• Hardware position tracing

Hardware tracing is used when the problem is related to a hardware

board where only the signaling to and from the board is wanted.

This function is especially useful when several program units are

cooperating to the same hardware position.
