Variable name Data type Default
value
Description
SamplingRate DD_SAMPLING
_RATE_ISD51x
ddFastTas
k_ISD51x
Sampling rate of the
trace.
SampleCount UINT 4000 Number of samples
to be traced per
channel.
SubSampling UINT 1 Multiplier to adjust
time dierence
between trace
samples.
SignalIDs ARRAY[0..7] of
UDINT
[0, 0, 0, 0,
0, 0, 0, 0]
IDs of the signals to
be traced. Available
in the list of
constants: SabTrace-
Signals.
TriggerID UDINT 0 ID of the signal
used for triggering.
Available in the list
of constants: SabTra-
ceSignals. Set to 0
for instant tracing.
TriggerPoint USINT 10 Amount of pre-
trigger history
[percentage].
Value range: 0–100
TriggerLevel REAL 0.0 Level at which is
triggered (in trigger
signal units).
TriggerSlope BOOL TRUE TRUE: Triggers on
rising slope.
FALSE: Triggers on
falling slope.
VAR_OUTPUT
Done BOOL The trace has
successfully been
recorded and read
from the device.
Busy BOOL The function block
is not nished and
new output values
are to be expected.
CommandA-
borted
BOOL Trace has been
aborted successfully.
Error BOOL An error has
occurred within the
function block.
ErrorInfo DD_ERROR_ISD51x Error identication
and instance
identier.
See
chapter 6.5.2.3 Error
Indication.
Variable name Data type Default
value
Description
Status USINT Holds the state of
the tracing process
(valid while Busy is
TRUE):
0 = Conguring the
trace.
1 = Trace
congured and
started.
2 = Waiting for
trigger.
3 = Triggered;
Waiting for
completion of the
trace.
4 = Uploading trace
data.
5 = Trace data
received
successfully.
TraceLength UDINT Length of trace data
that has been
uploaded [Byte]. 1
sample (REAL) is 4
Bytes long.
Table 6.84 DD_Trace_SAB
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).
