Description Signal
Interlock, HSM On,
HSM High The value reveals the state of the associated control when data is acquired.
In the case of Run/Stop and Hold signals, the values may not change
state since acquisition occurs only while the program is being run. These
signals may be useful in calculated signals.
Records the number of segments executed in the selected channel. (channel) Integer
Count
Note:
This signal measures the same value as (channel) Count, however,
it has greater resolution at higher segment counts (for instance,
counts greater than 16 million segments).
Note:
The count for a time history output increments once for each point
in the associated time history file.
Records the signal that goes to the valve driver. (channel) Output
Records various types of sensor feedback signals in engineering units.
Force and Displacement are typically sensor signals. (channel) Sensor
signals
Records the number of segments executed in the selected channel. (channel) Count
Note:
This signal is a floating point number. Its resolution decreases
significantly at higher segment counts (for instance, counts greater
than 16 million segments).
Records the control mode error signal in engineering units. This signal
shows the difference between the Channel Name Command and the
Channel Name Control Mode Name signals. (channel) Error
Records the absolute value of the Error signal in engineering units.
Absolute means negative becomes positive and positive remains positive.
This signal is always positive. (channel) Abs. Error
Time and Rollover Time signals
Time and Running Time signals are useful for recording the duration of tests. They may also be useful for
providing a time reference for data acquisition for tests of short duration. However, as the length of a test
increases, their suitability as a time reference for data acquisition decreases. This is because Time and
Running Time are floating point numbers, and their resolution decreases as they increase in value.
For instance, when the Time signal runs continuously for approximately six months, or about 16 million
seconds, its resolution drops to one second - which is far too coarse to be used as a time reference at
typical data acquisition rates.
To obtain a time reference with suitable resolution for longer tests, use Rollover Time or Running Rollover
Time. These signals are also floating point numbers, but they rollover (reset to zero) every hour (3600
