Example

When R031 is ON, the lower limit operation is executed for the data of RW019 by the data of D1220, and the result is stored in RW022.

C (RW022)

A (RW019)

Lower limit B (D1220)

When RW019 is -1000 and D1220 is -1800, -1000 is stored in RW022 and R0041 is OFF. When RW019 is 800 and D1220 is 1200, the limit value 1200 is stored in RW022 and R0041 is ON.

Note

•This instruction deals with the data as signed integer (-32768 to 32767).
