Program examples
1. Program example 1
In the program example shown below, the BCD data set in X020 to X037 is controlled by the zone from “-1000” to
“+1000”, and the controlled value is output to D1 when X000 turns ON.
Operation
• In the case of “D0 < 0”, “D0 + (-1000)” is output to D1.
• In the case of “D = 0”, “0” is output to D1.
• In the case of “D0 > 0”, “D0 + 1000” is output to D1.
2. Program example 2
In the program example shown below, the BCD data set in X020 to X057 is controlled by the zone from “-10000” to
“+10000”, and the controlled value is output to D11 and D10 when X000 turns ON.
Operation
• In the case of “(D1, D0) < 0”, “(D1, D0) + (-10000)” is output to (D11, 
D10).
• In the case of “(D1, D0) = 0”, the “0” is output to (D11, D10).
• In the case of “(D1, D0) > 0”, “(D1, D0) + 10000” is output to (D11, 
D10).
