024-372 IOT-ESS Communication Fail 22 RAP

BSD-ON: BSD 3.1 - ESS - MCU Communication
BSD-ON: BSD 16.1 - ESS
Sub System Fail. Sending error detected by Controller (Incorrect parameter instruction). An
illegal instruction for IOT Port No., Timeout Time, Pointer, or Transfer Size was detected.
Procedure
• Turn the power OFF then ON.
• Ensure that the customer is programming a job within the parameters of the machine uti-
lizing the UI.
• Disconnect then reconnect the IIT, Control Panel, ESS, MCU all PWBs connected to them
(RAM, Firmware module, EEPROM)
• Check the sw version of the controller sw - update if required
• Replace MCU PWB (PL 18.2)
• Replace ESS PWB (PL 35.2) (If not fixed by this, reinstall the original ESS & MCU)
