ARAMETER
All of the available I/O functions (except setpoints) have one or more
weigh mode accessible parameters associated with them. These
parameters are accessed starting at parameter 50 with the channel
number appended as an instance. For example, to access the first
parameter for channel 3, parameter 50.3 would be specified. Some
functions provide for more than one accessible parameter, in which case
these are referenced as parameter 51 and 52. The default name for I/O
parameter 50 - 52 are 'PIOAX', 'PIOBX', and 'PIOCX' respectively, where
the 'X' indicates the channel number.

EFERENCING
Any setup mode that allows parameters to be specified, such as analog
output (P17X), selectable parameters (P30X), Input Interpreter (P222),
Database columns (P7XX), custom transmits (P1XXX), setpoints (P51XX),
etc may specify these parameters. Macro commands that allow a
parameter reference may also use these parameters.

To view any of these parameters, enter the parameter number, a period,
then the channel number, followed by [SELECT]. If a name has been
programmed for that parameter then the name is displayed in the dot
matrix portion of the display.
A time measurement of one millionth (0.000001)
of a second. 1000 µs equals one milli-second.
One cycle of a signal, often measured in milli-
seconds.
The measure of how many cycles of a signal
occur in one second. Frequency is usually
measured in Hertz (Hz) which is equivalent to
cycles per second. Frequency can be calculated
by taking the inverse of the period of a waveform.
For example, if a signals period is 2.13 ms
(0.00213 seconds), the frequency is 1/.00213 =
469.48 Hz.
The proportion of a signal that is high as
compared to the signal's period. For example, if
the period of a signal is 2.5 ms and the high time
is 1 ms, then the duty cycle is 1 ÷ 2.5 = 0.4, which
can also be expressed as 40%.
