cause : I2C bus error occurred comes when communications error with an EEPROM or A/D converter. Fault value (r0949, interpret hexadecimal): 80000000 hex: internal software error & 00000001 hex ... 0000FFFF hex: module fault.
Re fault value = 80000000 hex: upgrade firmware to later version.
Re fault value = 00000001 hex ... 0000FFFF hex: replace the module.
