F_Trig incorrectly provides 'High' signal at the output (elimination)

Which products are affected?
EVS93xx-EI (Servo PLC Version 6.5 DSMC control board)
EVS93xx-ET (Servo PLC Version 6.5 DSMC control board)
EPL-10200 EI (Drive PLC Version 6.5)

Eliminated function restriction:
The output of the 'F_Trig' function block no longer indicates an incorrect 'High' signal for the first PLC cycle.
 
Which products are affected?
EVS93xx-EI (Servo PLC Version 6.2 DSMC control board)
EVS93xx-ET (Servo PLC Version 6.2 DSMC control board)
EPL-10200-EI (Drive PLC Version 6.2)

What happens?
For one cycle the 'F_Trig' function block incorrectly indicates a 'High' signal at output 'F_TrigInst.Q'.

When does the problem occur?
The error only occurs in the first cycle after the initialisation phase of the target system, e. g. after switching on the supply voltage. The error does not occur anymore in the further execution of the PLC program.

Possible diagnostics?
None.

Short-term measures/recommendations?
In the application, the evaluation of the F_Trig output (F_TrigInst.Q) is to be avoided in the first cycle.

Evaluation:
The error occurs immediately during initial commissioning and can be avoided by low programming efforts.
