409 Position depending delay
Description
The block supplies the position-dependent delay of a binary signal. The position
value on the input
X-act is acquired for an edge of the input signal In . If the
difference between X-act and the acquired position exceeds the value on X-
delay , the output signal Out is set. The amount of the difference is considered.
The output signal on Out is retained until the input signal on In becomes inactive.
If the signal on In becomes inactive before Out was set, Out remains active for
one cycle ( A150 ).
Input EdgeSel contains the setting of whether the rising or falling signal edge is
to be acquired on the input In . When EdgeSel contains the value 0, the rising
edge is acquired. When EdgeSel contains the value 1, the falling edge is
acquired.
The procedure can be retriggered (i.e., an additional rising or falling edge of the
input signal within the delay period will start the procedure again).
An active signal on the input
Reset resets the block asynchronously. It remains
in the reset state as long as the reset signal is active.
The input
UseInTS contains the setting of whether the input timestamps on
InTimeSt and X-Act-TS will be used.
A timestamp with which a delay of the output signals can be corrected by the
cycle time (
A150 ) is output on the output OutTS .
The status of the block can be queried on the output State .
Inputs
No. Name Datatype Scaling Description
1 Reset B –
Reset the block function.
0:inactive = normal operation
1:active = reset
2 EdgeSel U8 –
Selection of the edge on In which will trigger acquisition of the actual
position.
0:inactive = rising edge
1:active = falling edge
3 In B –
Input signal which is edge-triggered to start acquisition of the actual
position
4
UseInTS
B –
0: No timestamp
1: Use timestamp
5 InTimeSt U16 1LSB = 1us Timestamp of the input signal on In
6
X-Act
P64 Skal.-Fkt. 8 Actual position
7 X-Act-TS U16 1LSB = 1us Timestamp for actual position
8 X-delay P64 Skal.-Fkt. 8 Delay distance
Outputs
No. Name Datatype Scaling Description
9 Out B – Output signal
10 OutTS U16 1LSB = 1us Timestamp for the output signal
11 InOld B – Intermediate storage for edge recognition of the input signal
12 X-actOld I32 – Intermediate storage for speed measurement
13 X-edge I32 – Acquired start position
14 State U8 –
Output of the state code
0: Wait for the set signal edge
1: Delay distance running. Input signal is logically active. (Level
depends on the mode.)
2: Delay distance running. Input signal is logically inactive. (Level
depends on the mode.) Retriggering possible.
3: Delay distance expired. Output signal is active as long as the input
signal is logically active. When the input signal becomes logically
inactive, the state code changes to 0.
