Dynamic minimum (Dmn) and dynamic maximum (Dmx)
functions
The dynamic minimum (dmn) and dynamic maximum (dmx) functions
assign values to dimensions based on the minimum or maximum
values of dynamically sampled channels or dimensions. The sampled
values can be assigned directly, or can be used as triggers to assign a
value from a second source.
ND 2100G channel inputs are sampled many times per second and
the system updates and retains the minimum and maximum values
encountered in the sampling process. Minimum and maximum values
are evaluated simultaneously during sampling. Dynamic minimum and
maximum values can be calculated for any term or collection of terms.
Pressing the ENTER button or the Trip function stores the minimum
and maximum values.
To insert a dmn or dmx function:
U
Press the OTHER... soft key
U
Press the DMN or DMX soft key
Assigning a sampled value.
Assigning a second value.
Dmn function syntax
A = dmn(Sampled value)
Assigns the sampled minimum value.
A = dmn(Sampled value, second source)
Assigns the second source value when the sampled value is at the
minimum.
Dmx function syntax
A = dmx(Sampled value)
Assigns the sampled maximum value.
A = dmx(Sampled value, second source)
Assigns the second source value when the sampled value is at the
maximum.
Due to the relatively low sample rates of the dmn and dmx
functions, surfaces must be moved slowly during the
sampling process to insure that all points are evaluated.
Applications that require faster sample rates and have
appropriate input devices should use the HwDmn or
HwDmx function described Refer to "HwDmn and
HwDmx functions" on page 245.
