Max Gateway/Mailbox Modules Exceeded

Wago · PFC200 PLC

What does 1 (Argument: 14) mean?

The maximum number of gateway or mailbox modules allowed in the system has been exceeded. This configuration limitation prevents the system from functioning correctly, as it cannot properly manage or communicate with an excessive number of these specialized communication modules.

Common Causes

  • Too many gateway or mailbox modules physically connected to the controller.
  • System configuration attempting to utilize more gateway or mailbox modules than supported by the controller's hardware or firmware.
  • Incorrect module type identification, leading to miscounting.
