Instantiation and Usage Example

This figure shows an instance of the Bistable_Valve function block:

Limitations

When forced enable is active (xFrceEn), the valve is forced in to the default position (xPosDflt) only for the time iFbckDly seconds. It is reset if an appropriate feedback signal is activated or interlock signal is removed or the q_xErr output is acknowledged.

Ensure that appropriate feedback signal is activated before executing the block; else an unknown position error is detected after a time delay of iFbckDly seconds.
