o_wDiagCode
A program operation is suspended while the operation status of the CPU module is in STOP or PAUSE. Consequently,
measurement of the InternalTimer elapsed time is stopped.
Error behavior
In the event of an error, the output signals behave as listed below.

Description, output setting
i_bS_Button1 was ON on FB activation.
i_bS_Button2 was ON on FB activation.
The signals at i_bS_Button1 and i_bS_Button2 were ON
on FB activation.
i_bS_Button1 was OFF and i_bS_Button2 was ON after
500ms in state 8005H or 8006H.
i_bS_Button1 was ON and i_bS_Button2 was also ON
after 500ms in state 8005H or 8006H. This state is only
possible when the states of the inputs (S_Button1 and
S_Button2) change from divergent to convergent (both
ON) simultaneously when the timer elapses (500ms) at
the same cycle.
i_bS_Button1 was ON and i_bS_Button2 was also ON
after 500ms in state 8005H or 8006H. This state is only
possible when the states of the inputs (S_Button1 and
S_Button2) change from divergent to convergent (both
ON) simultaneously when the timer elapses (500ms) at
the same cycle.
Action
Release i_bS_Button1 and
i_bS_Button2.
Release i_bS_Button1 and
i_bS_Button2.
If the safety cycle time is long, the
safety input refresh is delayed and an
error may occur. Set the shorter value
to the safety cycle time.
