7 Application Instructions API 50-99 Program Example 2: 1. M1161 = On: The 8-bit conversion mode 2. When X0 = On, convert the 4 hex values in D10 into ASCII codes and send the result to registers starting from D20. M1000 M1161 X0 3. Assume (D10) = 0123 H ‘0’ = 30H ‘4’ = 34H ‘8’ = 38H (D11) = 4567 H ‘1’ = 31H ‘5’ = 35H ‘9’ = 39H (D12) = 89AB H ‘2’ = 32H ‘6’ = 36H ‘A’ = 41H (D13) = CDEFH ‘3’ = 33H ‘7’ = 37H ‘B’ = 42H 4. When n = 2, the bit structure will be as:
D10=0123 H 0 1 2 3 ASCII code of D20=2 is 32H 3 2 ASCII code of D21=3 is 33H 3 3 DVP-PLC APPLICATION MANUAL 7-121 n D K9 K10 K11 K12 K13 K14 K15 K16 D20 Low byte “B” “A” “9” “8” “F” “E” “D” “C” D20 High byte “4” “B” “A” “9” “8” “F” “E” “D” D21 Low byte “5” “4” “B” “A” “9” “8” “F” “E” D21 High byte “6” “5” “4” “B” “A” “9” “8” “F” D22 Low byte “7” “6” “5” “4” “B” “A” “9” “8” D22 High byte “0” “7” “6” “5” “4” “B” “A” “9” D23 Llow byte “1” “0” “7” “6” “5” “4” “B” “A” D23 High byte “2” “1” “0” “7” “6” “5” “4” “B” D24 Low byte “3” “2” “1” “0” “7” “6” “5” “4” D24 High byte “3” “2” “1” “0” “7” “6” “3” “2” “1” “0” “7” “3” “2” “1” “0” “3” “2” “1” no “3” “2” change “3” “3” “2” “1” “0” “7” “6” “5” D25 Low byte “3” “2” “1” “0” “7” “6” D25 High byte “3” “2” “1” “0” “7” D26 Low byte “3” “2” “1” “0” D26 High byte “3” “2” “1” D27 Low byte “3” “2” D27 High byte “3” ASCI D10 D20 K4 0 0 0 0 0 0 0 1 0 0 1 0 0 0 1 1 0 0 0 0 0 0 0 0 0 0 1 1 0 0 1 0 0 0 0 0 0 0 0 0 0 0 1 1 0 0 1 1
