Default Description
value
ddFastTas Sampling rate of the
k_ISD51x trace.
4000 Number of samples
to be traced per
channel.
1 Multiplier to adjust
time difference
between trace
samples.
[0, 0, 0, 0, IDs of the signals to
0, 0, 0, 0] be traced. Available
in the list of
constants: SabTrace-
Signals.
0 ID of the signal
used for triggering.
Available in the list
of constants: SabTra-
ceSignals. Set to 0
for instant tracing.
10 Amount of pre-
trigger history
[percentage].
Value range: 0–100
0.0 Level at which is
triggered (in trigger
signal units).
TRUE TRUE: Triggers on
rising slope.
FALSE: Triggers on
falling slope.
The trace has
successfully been
recorded and read
from the device.
The function block
is not finished and
new output values
are to be expected.
Trace has been
aborted successfully.
An error has
occurred within the
function block.
Error identification
and instance
identifier.

6.5.8.16 DD_SimulateGuideValue_SAB

This function block is used to simulate a guide value
without a physical encoder connected. It can be conserved
as virtual master axis. Linear ramps are used for the
calculation of the position guide value. The simulated
value can be read by using the function blocks
DD_ReadPosGuideValueRef_SAB (see
chapter 6.5.8.17 DD_ReadPosGuideValueRef_SAB) and
DD_ReadVelGuideValueRef_SAB (see
chapter 6.5.8.18 DD_ReadVelGuideValueRef_SAB).
Object 0x2063: Guide value reference option code must be
set accordingly to enable the simulation functionality (see
chapter 8.18 Object 0x2063: Guide Value Reference Option
Code).
Default Description
value
Holds the state of
the tracing process
(valid while Busy is
TRUE):
0 = Configuring the
trace.
1 = Trace
configured and
started.
2 = Waiting for
trigger.
3 = Triggered;
Waiting for
completion of the
trace.
4 = Uploading trace
data.
5 = Trace data
received
successfully.
Length of trace data
that has been
uploaded [Byte]. 1
sample (REAL) is 4
Bytes long.
