Trace Function [52]
Description:
It defines the value for comparison with the variable selected in P0550.
The full range of the variables selectable as trigger is presented in the next table.
This parameter has no effect when P0552 = "Alarm", "Fault" or "DIx".

Description:
It defines the condition for starting the signal acquisition. The
For P0552=6 ("DIx" option), it is necessary to select the option "Trace Function" at one of the parameters from P0263

Notes:
- If P0552 = 6 and no DI is configured for "Trace Function", the trigger will not occur.
- If P0552 = 6 and several DIs were configured for "Trace Function", only one has to be active for the trigger
occurrence.

P0550* = P0551 The variable selected in P0550 is equal to the value adjusted in P0551
P0550* ≠ P0551 The variable selected in P0550 is different from the value adjusted in P0551
P0550* > P0551 The variable selected in P0550 is bigger than the value adjusted in P0551
