Function Blocks
In addition to the physical and transducer block, the digital valve controller contains the following function blocks.
D Analog Output (AO) Function Block—The analog output function block accepts the output from another function
block (such as a PID block) and transfers it as an actuator control signal to the transducer block. If the DO block is
selected, the AO block is not functional.
D Discrete Output (DO) Function Block—The discrete output function block processes a discrete set point and sends it
to a specified output channel, which can be transferred to the transducer block for actuator control. In the digital
valve controller, the discrete output block provides both normally open or closed control and the ability to position
the valve in 5% increments for coarse throttling applications. If the AO block is selected, the DO block is not
functional.
D Analog Input (AI) Function Block—The analog input function block monitors the signal from a DVC6200p sensor or
internal measurement and provides it to another block.
D Discrete Input (DI) Function Block—The discrete input function block processes a single discrete input from a
DVC6200p and makes it available to other function blocks. In the digital valve controller, the discrete input function
block can provide limit switch functionality and valve position proximity detection.
D Alarm Transducer Block—The Alarm Transducer Block manages the device alarms. Active alarms are monitored and
displayed as active. Working with the Logbook Block those alarms active and configured are time/date stamped and
written to the Logbook block.
D Logbook Function Block—The Logbook Function Block will store any alarm that is active and configured to record an
occurrence of the alarm to the logbook. Logbook entries are written from active alarms in the Alarm Transducer
Block. Each Logbook entry is time/date stamped. A maximum of 260 log entries are allowed.
