Data Control Instructions Section 3-18
3-18-6 TIME-PROPORTIONAL OUTPUT: TPO(685)
Purpose 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 specified output.
This instruction is supported only by CS/CJ-series CPU Unit Ver. 2.0 or later.

Operands S: Input Word
Specifies the input word containing the input duty ratio or manipulated vari-
able. Bits 04 to 07 of C specify the input type, i.e., whether the input word con-
tains 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.)
• Input duty ratio: 0000 to 2710 hex (0.00% to 100.00%)
• Input manipulated variable (See note.): 0000 to FFFF hex (0 to 65,535
max.) (Bits 00 to 03 of C specify the manipulated variable range, i.e., the
number of valid bits in the manipulated variable. Specify the same number
of bits as specified for the output range setting in PID(190).)
Note If S is a manipulated variable, specify the word containing the manip-
ulated variable output from a PID(190) or PIDAT(191) instruction.
