Simulate device variables
Simulate device variables is only available in HART Revision 7 mode (“HART 7”).
In HART 7, it is possible to temporarily set a device variable to a user-defined fixed value for
testing purposes. After the simulated variable method is exited, the device variable is
automatically returned to a live value.
Simulate Output State
The
Output State
device variable can be temporarily overridden to be “off” or “on”.
Simulate Sensor State
The
Sensor State
device variable can be temporarily overridden to be “dry” or “wet”.
Simulate Sensor Frequency
The
Sensor Frequency
device variable can be temporarily overridden with an entered
frequency in the range 0 to 3000 Hz.
