• Total number of I/O points set in the I/O tables exceeds the maximum allowed for the CPU Unit (details bits: 000).
• More than 32 interrupt inputs are configured (details bits: 001).
• Three or more Pulse I/O Modules were connected to a CJ2M CPU Unit (details bits: 100).
• The number of Expansion Racks exceeds the maximum allowed (details bits: 101).

Click steps to track your progress.

1. 1

   Correct the I/O configuration (reduce I/O points, interrupt inputs, Pulse I/O Modules, or Expansion Racks/Units per Rack) according to the details provided in Auxiliary Area A407.13 to A407.15.

2. 2

   After correcting the configuration, cycle the power supply OFF and back ON.
