To run a sequence file press "Enable Sequencer", this button will turn to "Disable
Sequencer" once the sequence starts. (The sequencer should be activated if it
was disabled but not necessary to change from one sequence to another). The
sequence will repeat itself indefinitely until disabled or the software exited. If
enabled, the sequence will continue to run after the "close sequencer window"
button is pressed.
If desired, the valve sequence can be forwarded to the next step of the sequence
by pressing the "run next step" button. To stop the sequencer file, use the
"Start/Stop Sequencer" menu item under the "Action" menu. This will leave all
valves in their current state. In some situations, it is convenient to program the
last step in the sequence to be a safe or default valve state. The sequencer can
be advanced to the last step should the user need to put the solenoid or rotary
vales into a safe/default state. The "Reset All Valves" de-activates all valves.
Using the "Hide Sequencer Interface" closes the window, but if the sequencer is
enabled, it will continue to run in the background. To jump to a particular step,
increment the "run step 3" and click "Apply."
Both solenoid and rotary valve codes are recorded in columns in the output data
files indicating the active valve configuration respective to when data is taken.
These codes can be used as event timing flags. For example, if no solenoid
valves are present, the codes will be recorded regardless of whether a valve is
connected or not.
