The Less Than or Equal (LEQ) instruction in ladder logics is used to test whether one value (source A) is less than or equal to another (source B).
If the value at source A is less than or equal to the value at source B, the instruction is logically true.
Less Than or Equal (LEQ) Instruction
Source A must be an address.
Source B can be either a program constant or an address.
Values are stored in two’s complementary form.
