About continuous execution: time propagation

If the PV overide is disabled, the input's value, time, and quality (VTQ) is used to update PVAuto and PV.

If the PV overide is enabled and PV.Mode is Auto, the input's VTQ is used to update PVAuto and PV.

If the PV overide is enabled and PV.Mode is Manual, the input's VTQ is used to update PVAuto. PV stays at the last user set value, the current time of the set, and a quality of UNCERTAIN.

If analog output is enabled:

• a PV value set request's original VT with good quality shall be forwarded to the output.

• a PV timestamp set request shall cause the PV's current value, the provided timestamp and good quality to be forwarded to the output.

If you configure the object as an analog regulator:

• SP's feedback attribute's VTQ is used to update SP.

• An SP value set request's original value and time stamp with good quality is forwarded to the WriteValue of the input/output. SP is not updated.

• An SP time stamp set request causes the SP's current value, the provided time stamp, and good quality to be forwarded to the WriteValue of the input/output. SP is not updated.
