Program example
1. Program example 1
In the program example shown below, the BCD data set in X020 to X037 is controlled by the dead band from
"-1000" to "1000", and a controlled value is output to D1 when X000 turns ON.
Operation
1) In the case of "D0 < (-1000)", "D0 - (-1000)" is set to D1.
2) In the case of "(-1000 ≤ D0 ≤ 1000", "0" is output to D1.
3) In the case of "1000 < D0", "D0 - 1000" is output to D1.
