■ CP1W-DA041/CP1W-DA042
■ CP1W-DA021
Connect the Analog Output Unit to the CPU Unit.
Connect and wire Units.
Create a ladder program.
• Connect Analog Output Units.
• Wire to analog input devices.
• Write set data to output words
CP1W-DA041/DA042: Words (n+1, n+2)
CP1W-DA021: Word (n+1)
• Set use of outputs.
• Select output signals using range codes.
• Write D/A conversion values to output words
CP1W-DA041/DA042: Words (n+1 to n+4)
CP1W-DA021: Words (n+1, n+2)
MOV(021)
Word (n+1) Set data (outputs 1, 2)
Word (n+2) Set data (outputs 3, 4)
Word (n+1)
Word (n+2) Analog output 2 conversion value
Word (n+3) Analog output 3 conversion value
Word (n+4) Analog output 4 conversion value
