Missing Parenthesis

Kuka · KSS 5.2

What does 2309 mean?

This error occurs when the KRL compiler interprets a line of code as a subprogram call, but detects that the expected opening parenthesis '' character is missing. This is a syntax error that prevents the compiler from correctly parsing the subprogram call, leading to a compilation failure.

Common Causes

  • Syntax error in parameter configuration string input.
  • Missing closing parenthesis in a command string for a peripheral device.
  • Incorrectly formatted data packet received from a sensor or actuator.
  • Configuration error in the control logic where a grouped parameter lacks a closing delimiter.
  • Software bug in the Human-Machine Interface (HMI) or Programmable Logic Controller (PLC) code processing.
