The positioner’s tag is shown in the PD Tag field. The current operating state of the
positioner is shown the text box. Individual block modes are displaye for each of the
positioners internal function blocks. The valve position Set Point is displayed by the graphi-
cal position of a slider and numerically to two decimal places. Below the setpoint display,
the target position and actual position are shown as a slider and bar respectively, with
values shown to two decimal places.
The Target Position is derived from the Set Point signal based on the parameters defined in
Configuration Services, as well as the characterization and the configuration of air-to-open
or air-to-close. If linear characteristics and air-to-open are configured, without limits, the
position setpoint is equal to input signal expressed in percentage. When the configuration
is nonlinear with limits, the incoming setpoint and the target position differ because the
Analog Output (AO) Block and Transducer (TB) Block re-compute the target to conform.
