(2) The following program performs zone control by applying negative and positive bias values of -10000 to 10000 for the
data set at D0 and D1 and stores the result of control at D10 and D11 when X1 is turned ON.

[Operation]
• The value (D1, D0) + (-10000) is stored at (D11, D10) if (D1, D0) 0.
(D1,D0) -12345 (D11,D10) -22345
• The value 0 is stored at (D11, D10) if (D1, D0) 0.
• The value (D1, D0) + 10000 is stored at (D11, D10) if 0 (D1, D0).
(D1,D0) 50000 (D11,D10) 60000
: Input values for scaling or head number of the device where input values are stored(BIN 16/32 bits)
: Head number of the devices where scaling conversion data are stored(BIN 16/32 bits)
: Head number of the devices where output values depending on scaling are stored(BIN 16/32 bits).
Function
SCL(P)
(1) This instruction executes scaling for the scaling conversion data (16-bit data units) specified by with the input value
specified by , and then stores the operation result into the devices specified by .
The scaling conversion is executed based on the scaling conversion data stored in the device specified by and up.
