2. Program example 2
In the program example shown below, the BCD data set in X020 to X057 is controlled by the limit values
"10000" and "1,000,000", and the controlled value is output to D11 and D10 when X000 turns ON.
Operation 1
1) In the case of "(D1, D0) < 10000", "10000" is set to (D11,
D10).
2) In the case of "10000 ≤ (D1, D0) ≤ 1,000,000", the value of
(D1, D0) is output to (D11, D10).
3) In the case of "1,000,000 < (D1, D0)", "1,000,000" is output
to (D11, D10)
