Equal   

The Equal function block compares the value of input A to input B.

If input A is equal to input B : power will flow through the function block.

If input A is not equal to input B: power will not flow through the function block.

According to the above example:

• If MI 1 is equal to MI 3; then MB 55 will go to logic "1" (ON).

• If MI 1 is not equal to MI 3; then MB 55 will go to logic "0" (OFF).

These values may be compared:

• Memory Integer (MI)

• Memory Long Integer (ML)

• Double Word (DW)

• System Operands:(SI) (SL) (SDW)

• Network System Integer (NSI)

• Constant Value #
