Internal Buffer Overflow (Inline Code Generation)

Wago · PFC200 PLC

What does 1 mean?

An internal buffer overflow has occurred during inline code generation, indicating that the maximum amount of data allowed for this process has been exceeded. This typically happens when the controller is trying to process too much I/O data or control logic due to an excessive number of I/O modules.

Common Causes

  • Excessive number of I/O modules connected to the controller, exceeding data handling capacity during inline code generation
  • Large amount of data processed during inline code generation within the controller
