024-357 IOT-ESS Communication 17 RAP

BSD-ON: BSD 3.1 - ESS - MCU Communication
BSD-ON: BSD 16.1 - ESS
IOT-ESS Communication Failure 17. ESS PWB detected a communication failure between
IOT and ESS.
Initial Actions
Power Off/On
Procedure
• Ensure that the customer is programming a job within the parameters of the machine uti-
lizing the UI.
• Check that connectors on the MCU PWB MCU PWB
35.2) are securely connected. 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. If the problem continues, reload Software
16).
• Replace ESS PWB (PL 35.2) (If not fixed by this, reinstall the original ESS & MCU)
• If the problem persists, replace the MCU PWB MCU PWB
