concat

 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. - Concatenate of strings.

Inputs

Input	Data Type	Range	Unit	Default	Description
IN_1	STRING				Any string variable or constant expression.
IN_N	STRING				Any string variable or constant expression.

Outputs

Output	Data Type	Range	Unit	Description
Q	STRING			Concatenation of all inputs.

Remarks

• 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 or FFLD "Free Form Ladder Diagram" Language, the block can have up to 16 inputs.
• In the IL "Instruction List" This is a low-level language and resembles assembly Language or ST "Structured text" A high-level language that is block structured and syntactically resembles Pascal Language, the function accepts a variable number of inputs (at least 2).
• Use the + operator to concatenate strings.
