OPERAND DESCRIPTIONS:

Process gain - A tuning parameter that specifies the proportional relationship of the process

variable (PV) and the valve output (VO). Gain = (

DPV) / (D VO). Gain values are 0, or 0.003906 to

127.996.

Process time constant - A tuning parameter that specifies the first order filter, where the time for

the process variable to change is 63.2 percent of the change in valve output minus the transport

delay. Time constant values are: 0, or 0.0042 to 134.23 minutes for the 4 hertz version controller; 0,

or 0.0017 to 53.69 minutes for the 10 hertz version controller; and 0, or 0.0009 to 26.84 minutes for

the 20 hertz version controller.

Process dead time - A tuning parameter that is equal to the actual "transport delay" of the

process in minutes. Dead time values are: 0, or 0.0644 to 2109.85 minutes for the 4 hertz version

controller; 0, or 0.0258 to 843.94 minutes for the 10 hertz version controller; and 0, or 0.0129 to

421.97 minutes for the 20 hertz version controller.

Reset - The name of the general register or discrete loadable function that contains the discrete

value used to reset the DTC function (0 = enabled, 1 = reset).

Comment - A comment up to 255 characters long.
