FBD Language Example
- In the FBD
"Function Block Diagram"
A function block diagram describes a function between input variables and output variables. A function is described as a set of elementary blocks Language, the block can have a maximum of 32 inputs.
FFLD Language Example
- In the FFLD "Free Form Ladder Diagram" Language, the input rung (EN) enables the operation.
- The output rung (ENO) keeps the same value as the input rung.
IL Language Example
- In the IL "Instruction List"
This is a low-level language and resembles assembly Language, the ADD instruction performs an addition between the current result and the operand.
- The current result and the operand must have the same type.
Op1: FFLD IN1
ADD IN2
ST Q (* Q is equal to: IN1 + IN2 *)
Op2: FFLD IN1
ADD IN2
ADD IN3
ST Q (* Q is equal to: IN1 + IN2 + IN3 *)
ST Language Example
Q := IN1 + IN2;
MyString := 'He' + 'll ' + 'o'; (* MyString is equal to 'Hello' *)
