Calculation Channel - Delphin Expert Logger Manual

Expert Logger
4.11.16 Calculation channel
This software calculates the input mathematical formula. Any number of
sources can be linked within the formula. Each source is represented by a
variable that can assume either a constant value or the value from the spe-
cified channel.
Method
1. Set the required variables with Add variable.
A variable named var0 is created by default, but its name can be changed.
2. Set whether the variable is to have a constant value (Manual value) or
whether the value is to be obtained from a channel (Channel).
3. Enter the formula expression in the field Formula.
Restrictions on variable names
1. The first character must be alphabetic (a...z/A...Z).
The subsequent characters must be alphanumeric (letters a...z/A...Z or
numbers 0..9) or an underscore (_).
2. Variable names must be unique (no repeat names in different channels).
3. A distinction is made between upper and lower case letters.
Input in the formula field must use the same syntax as for variable names,
otherwise the formula is invalid.
