Calculators (calculation modules) 3, 4

Description
Using the "Calculator 3" and "Calculator 4" function blocks (for SIMOCODE pro V PN and
pro V EIP basic units only), analog values can be processed according to the following
arithmetic:
Output = Input 1 [Operator 1] Input 2 [Operator 2] Input 3 [Operator 3] Input 4.
You can connect the corresponding analog signals to the 4 inputs "Calculator 3/4 - Inputs 1
to 4". As operators "Calculator 3/4 - Operator 1 to 3," you can choose one of the four
standard operators ("+", "-", "*," or "/").
With "Calculator 3/4 - Priority 1 to 3," you can specify the processing sequence (high,
medium, low). You must clearly define a priority for each operator. The priority determines
the processing sequence comparable to the placement of a term inside parentheses.
Example:
Output = I1 OP1 I2 OP2 I3 OP3 I4, where
● OP1 = "*"; Medium,
● OP2 = "+"; High,
● OP3 = "-"; Low
Associated equation: Output = (I1 * (I2 + I3)) - I4.
If you interconnect the input to the device-internal analog output data element "Output 1 -
Fixed level", the input is assigned the constant "Const x" (x = 1 - 4). In this case, the
respective edit field for the constant is activated. You can enter a value between 0 and
65535.
The "Calculator 3" and "Calculator 4" function blocks each consist of:
● Four analog plugs
● One analog socket
● Logic.
