In PID faceplate, need [1]ramp up and [2] ramp down button.
Project: - Front end up gradation from Advant Version (Unix, MOD System) to 800xA with MOD 300 connect (Windows).RAMP UP and RAMP DOWN feature is available in AC460 controller with Advant Station UNIX Based operating system.
Available: - In 800xA 5.1 Rev A FP1, in PID faceplate, Output value can be change by using up /down arrow from the keyboard but it requires keyboard entry ENTER key to accept the value in the output box.
Requirement: - [1] The function ramp up should work like, when the ramp up button is pressed the output of PID loop should increase directly (i.e., without pressing ENTER / any key).
[2] The function ramp down should work like, when the ramp down button is pressed the output of PID loop should decrease directly (i.e., without pressing ENTER / any key).
Explanation: - [1] If the ramp up button is (Pressed for 10 sec) keep on pressing then the output [example: - Output=10] of PID should keep on increase. Whenever ramp up button is depressed (after 10 sec) at that time the output should hold the last value [example: - Output may go to 50].
[2] If ramp down button is (Pressed for 10 sec) keep on pressing then the output[example: - Output=100] of PID should keep on decrease. Whenever ramp down button is depressed (after 10 sec) at that time the output should stop decreasing [example: - Output may come to 70].

What is a problem to remove "apply present" feature from the faceplate?
Open faceplate in "config view", go to "Buttons" tab and uncheck all checkboxes for "Apply present".
After that on button click the value should be write without "apply" confirmation.
