Sequence Step Data Exchange Automation Inputs
Elements consist of:
•
Selected Step of the Active Sequence
•
Selected Step Amount
•
Selected Step Shot Type
•
Selected Step Flow Rate
•
Selected Step Calibration
Sequence Step Data Exchange Automation Outputs
Elements consist of:
•
Desired Step of the Active Sequence
•
Desired Step Amount
•
Desired Step Shot Type
•

•
Desired Calibration
See the
EFR Sequence Step Data Exchange
for further explanations of the Sequence Step
Data Exchange Automation Outputs Elements and
Sequence Step Data Exchange Automation Inputs
Elements.
NOTE:
If the Desired Step of the Active Sequence
changes, the process of the Sequence Step Data
Exchange will start over again, as shown in the timing
diagram.
EFR Sequence Step Data
Exchange Elements
Desired/Selected Step of the Active
Sequence
Desired/Selected Step of the Active Sequence is a byte
used to define the sequence step information that can
be edited or read through the other elements of the
sequence step data exchanged. When reading or
writing to this element, the value will correspond with the
step that can be read or edited.
Example
: If 3 is shown, step 3 can be edited or read.
Desired/Selected Step Amount
Desired/Selected Step Amount is a 32bit integer used to
define the step amount for the Desired Selected Step of
the Active Sequence. When reading or writing to this
element, the sequence step amount has two decimal
places, and the units are always reflected by the integer
in Selected Sequence Step Shot Type.
Desired/Selected Step Shot Type
Desired/Selected Step Shot Type is a byte used to
define the step type for the Desired Selected Step of the
Active Sequence. The table below shows the
corresponding values and units that can be written or
read from the EFR.
* Continue means the EFR will not wait on an external
trigger from the Trigger I/O pin or the Start Current
Sequence/Step, Trigger Operator Mode bit. The EFR
will immediately continue into that step.
** Break means the EFR will wait on an external trigger
from the Trigger I/O pin or the Start Current
Sequence/Step, Trigger Operator mode bit before
moving into that step.
Desired/Selected Step Flow Rate
Desired/Selected Step Flow Rate is a 16bit integer used
to define the step flow rate for the Desired Selected
Step of the Active Sequence.
Desired/Selected Step Calibration
Desired/Selected Step Calibration is a 16bit signed
integer used to define the step calibration for the
Desired Selected Step of the Active Sequence. The
units for this are always reflected by the integer in the
Selected Sequence Step Shot Type.
