7.11 Character String Processing Instructions
Program example
• The following program uses the PR instruction to convert BCD 4-digit data (the value at W0) to decimal, and outputs it in
ASCII format to Y40 to Y48.
• The following program uses the PR instruction to convert BCD 8-digit data (the values at W10 and W11) to decimal, and
outputs it in ASCII format to Y40 to 48.
[Ladder Mode] [List Mode]
[Operation]
Conducts ASCII output of Y40 to Y48 by using the PR instruction when X0 goes ON.
Because SM701 is OFF, the PR instruction will output ASCII code until 00H is encountered.
