  You cannot use an SIS Final Control Element as part of your BPCS control strategy. You can use an LSDVC function block as a 2-state output to the valve in your SIF (there is no SIS AO). You cannot use this as part of your normal process operations. The SIS has a separate purpose from your process system, and the two can NEVER share instrumentation.
