The Arithmetic function block performs all four basic calculations:
• add
• subtract
• multiply
• Divide.
easy800 allows the use of up to 32 arithmetic function blocks.
An arithmetic function block does not require an enable or start signal and is
therefore not wired in a coil field of the standard circuit diagram. The function
block is provided with the two Boolean outputs mentioned above for
controlling the calculation result that you wire as contacts in the circuit
diagram.
Contacts and Coils
A closed contact indicates:
Contacts Meaning
Outside of the permissible value range
AR..CY
Result at output
AR..ZE

When using the function block in the circuit diagram for the first time, use
OK to automatically enter the general display of function block parameters,
as shown in the figure on the left. Enter the function block settings here.
The display contains the following elements:
Function block: Arithmetic, number 04

First value is associated with the value at I2 via the arithmetic operation, value range:
>I1
-2147483648 - 2147483647
Second value, -2147483648 - 2147483647
>I2
Outputs the calculation result, value range: -2147483648 - 2147483647
