TIME-PRO-
PORTIONAL
OUTPUT TPO --- Inputs the duty ratio or manipulated variable from the specified
word, converts the duty ratio to a time-proportional output based
on the specified parameters, and outputs the result from the spec-
ified output.
C: First Parameter Word
Bits 04 to 07 of C specify the input type, i.e., whether the input
word contains an input duty ratio or manipulated variable. (Set
these bits to 0 hex to specify a input duty ratio or to 1 hex to
specify a manipulated variable.)
The following diagram shows the locations of the parameter
data.
R: Pulse Output Bit
Specifies the destination output bit for the pulse output.
Normally, specify an output bit allocated to a Transistor Output
Unit and connect a solid state relay to the Transistor Output
Unit.
SCALING SCL @ Converts unsigned binary data into unsigned BCD data according
to the specified linear function.
