S : Comparison of binary floating point numbers value 1. S
1
binary floating point numbers value 2. D: Results of comparison, occupies 3
consecutive points.
When binary floating point number 1 is compared with comparative binary
floating point number 2, the result of comparison (>, =, <) will be expressed in D.
If the source operand S
transform the constant to a binary floating-point number for the purpose of
comparison.
When the designated device is M10, it will automatically occupy M10–M12.
When X0=On, the DECMP command executes, and one of M10–M12 will be On.
When X0=Off, the DECMP command will not execute, and M10–M12 will remain
in the X0=Off state.
If results in the form of ≥, ≤, or ≠ are needed, they can be obtained by series and
parallel connection of M10–M12.
Please use the RST or ZRST command to clear the result.
