Integer Comparison

Comparing integers performs a comparison operation on 16-bit fixed-point numbers. You can use this command as an ordinary contact. This command compares the inputs IN1 and IN2 according to the type of comparison that you select in the browser. The following table lists the valid comparisons.

If the comparison is true, then the result of the logical operation (RLO) of this
function is 1. Otherwise, it is 0. Negative exit
no comparison as this result can be obtained
using the appropriate inverse comparison function.

LAD block	Options	Data type	Memory area	Description
	IN1	Int	I, Q, M, D, L	First value to compare
	IN2	Int	I, Q, M, D, L	Second value compared

Example and bits of integer comparison status word

Output Q 4.0 is set if the following conditions are true: 1 is equal to the state of the signal at inputs I 0.0 and I 0.1, and MW0 <> MW2, and equal to 1 the state of signal at input I 0.2

Comparing double integers

The Comparing double integers command performs a comparison operation on 32-bit fixed-point numbers. In all other respects, she is no different from the previous team. the type of comparison you choose in the browser. The table above lists valid comparisons.

LAD block	Options	Data type	Memory area	Description
	IN1	Dint	I, Q, M, D, L	First value to compare
	IN2	Dint	I, Q, M, D, L	Second value compared

Example and bits of the word of the comparison of double integers

Output Q 4.0 is set if the following conditions are: Equals 1 signal state at inputs I 0.0 and I 0.1 and MD0 = MD4 And equals 1 signal state at input I 0.2

Floating point comparison

The command Comparing floating-point numbers starts the comparison operation. In all other respects, she is no different from the previous team. the type of comparison you choose in the browser. The table above lists valid comparisons.

LAD block	Options	Data type	Memory area	Description
	IN1	REAL	I, Q, M, D, L	First value to compare
	IN2	REAL	I, Q, M, D, L	Second value compared

Example and bits of the floating-point comparison state word

Output Q 4.0 is set if the following conditions are met: Equals 1 signal state at inputs I 0.0 and I 0.1 and MD0 = MD4 And is equal to 1 signal state at input I 0.2
