Program example
• The following program performs the dead band control by applying the lower and upper limits of 0 and 1000 for the data set
in BCD at X20 to X2F and stores the result of control at D1 when X0 is turned ON.
• The following program performs the dead band control by applying the lower and upper limits of -10000 and 10000 for the
data set at D0 and D1 and stores the result of control at D10 and D11 when X0 is turned ON
[Ladder Mode] [List Mode]
[Operation]
• "0" is stored at D1 if 0  D0  1000. (example: D0 = 500  D1 = 0)
• The value of (D0) - 1000 is stored at D1 if 1000 < D0. (example: D0 = 7000  D1 = 6000)
[Ladder Mode] [List Mode]
[Operation]
• The value (D1, D0) - (-10000) is stored at (D11, D10) if (D1, D0) < (-10000). (example: (D1, D0) = -12345  (D11, D10) = -2345)
• The value 0 is stored at (D11, D10) if -10000  (D1, D0)  10000. (example: (D1, D0) = 6789  (D11, D10) = 0)
• The value (D1, D0) -10000 is stored at (D11, D10) if 10000 < (D1, D0). (example: (D1, D0) = 50000  (D11, D10) = 40000)
