Add
To add an enable input and enable output to the instruction, select [With EN/ENO] from the
"Instructions" pane (LD, FBD or IL editor). To reuse an instruction select "Recently used" from the
context menu or press <Ctrl>+<Shift>+<v> in the programming window.
PLC types Availability of ADD (see page 1335)
 All operands must be of the same data type.
 This function can be expanded to a maximum of 28 input contacts.
Data type I/O Function
INT, DINT, REAL 1st input augend
INT, DINT, REAL 2nd input addend
INT, DINT, REAL output as input sum
In this example the input variables (summand_1, summand_2 and enable) have been declared.
Instead, you may enter constants directly into the function (enable input e.g. for tests).
Description
This function adds the input variables IN1 + IN2 +... and writes the addition result into the output
variable.
Data types
Example
In this example, the same POU header is used for all programming languages. For an example
using IL (instruction list), please refer to the online help.
POU header
All input and output variables which are required for programming the function are declared in the
POU header.
Body
If enable is set (TRUE), summand_1 is added to summand_2. The result is written into sum.
