6. Function blocks
6.1 Manufacturer function blocks
6.1.3.2 AR - Arithmetic
General
easyE4 base devices provide 32 arithmetic function blocks,
AR01 through AR32. These function blocks can be used to carry
out the four basic arithmetic operations: addition, subtraction,
multiplication, and division.
Operating principle
The function block will apply the selected arithmetic operation to the values at function
block inputs I1 and I2. If the calculation result exceeds the value range that can be rep-
resented, overflow signal contact CY will close and function block output QV will con-
tain the value of the last valid operation. When the function block is called for the first
time, the value at function block output QV will equal zero.
