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.
Parameter Descriptions
VALUE TRUE
The value that OUTPUT assumes when input is TRUE.
VALUE FALSE
The value that OUTPUT assumes when input is FALSE.
DIGIN 1 (C6) to DIGIN 3 (C8)
Refer to the DIAGNOSTICS function block description, page 6-18.
OUTPUT
(DESTINATION TAG)
The destination Tag No. of the assumed value.
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.
