The AO block acts as a positioner for the valve and actuator. The positioning action is initiated by
setting the DO function to Position Control Enable through the DO blocks, or by setting the Control
Mode (Transducer block parameter 65) to AO only. Each time the positioner is enabled, the actuator
will move to the value set in the AO block, provided the actuator Local/Remote selector is in the
Remote position.
Note:
The block option for IO_OPTS must be set to PV for BKCal_Out for correct operation of a
control or positioning function. The AO block will only control the actuator position when the
DO setting is for Position Control Enable or the appropriate Transducer block parameter is set
for AO only mode.
