Use ST Expressions in Graphic Language
Kollmorgen Automation Suite - Integrated Development Environment enables Enable signal for the drive, Hardware-Enable with 24V signal to X8, Software-Enable command by setup Software, fieldbus or permanently set.
Both are required for enabling the drive. any complex ST Structured text - A high-level language that is block structured and syntactically resembles Pascal. expression to be associated with a graphic element in either FFLD or FBD Function block diagram - Describes a function between input variables and output variables. A function is described as a set of elementary blocks. language.
- This feature makes it possible to simplify FFLD and FBD diagrams when a trivial calculation has to be entered.
- It also enables you to use graphic features for representing a main algorithm as text is used for details of implementation.
- Expression must be written in Structured Text (ST) language.
- An expression is anything you can imagine between parentheses in an ST program The act of performing a sequence of instructions or commands..
- The ST expression must fit the data type required by the diagram (e.g., an expression put on a contact must be Boolean).
- An expression is anything you can imagine between parentheses in an ST program
FBD Language Example
A complex ST expression can be entered in any variable box of an FBD diagram if the box is not connected on its input.
FFLD Language Example
A complex ST expression can be entered on any kind of contact and on any input of a function A function calculates a result according to the current value of its inputs.
A function has no internal data and is not linked to declared instances. or function block A function block groups an algorithm and a set of private data.
It has inputs and outputs..
