Controller that the module was added to needs to be cold started before it will recognize the module


Adding xP expansion modules to either an ACX57xx or a BCX9640 states in the module reference guide that the modules can be added to controllers while the power is applied EXCEPT for the ACX57xx or the BCX96xx models.

  1. Power down the ACX57xx or the BCX96xx
  2. Add module to the ACX57xx or the BCX96xx
  3. Re-apply power to the controller
  4. Green CPU light on module should blink, if not follow next step.
  5. Re-load of controller.
