DIGITAL INPUTS
This function block allows the user to
control the digital operating parameters
of the software. The digital input can be
configured to point to a destination
location and to set that destination TRUE
or FALSE depending upon programmable values.
Functional Description
The destination for a digital input can be any valid Tag No, this means that a digital input can be
used to select one of two values for a given parameter. It is also possible to treat the values for
TRUE and FALSE as destination tags from other functions or inputs.
With regard to destinations
expecting logic parameters, 0.00% is
regarded as Logic 0 and any other
value is regarded as Logic 1. This
refers to the values set in both
VALUE TRUE and VALUE
FALSE.
Inverting the digital input is
therefore simple; set VALUE TRUE
to 0.00% and VALUE FALSE to
0.01% or any other non-zero
number.
