Device ID 83h
Fault occurred Time 4 Byte msec Time
Status Information 1 ~ 4 Byte
Data Check Sum Check Sum
- Checksum = (Command 1Byte + Sub Command 1Byte + Device ID 1byte + Fault
occurred t time 4Byte + Data 1~4Byte) / 256 ⇒ The residual
※ Checksum is the sum of each bytes not to include OVERFLOW.
- SOE Event is classified and presented on the last 7 bits of Sub Command
- The MSB (Bit 7) of Sub Command is EOD which stands for End Of Data
EOD=0 : The present frame is the last SOE data
EOD=1 : Other SOE data exists in the buffer
- Fault occurred time : It is the value of 4 Byte Long Integer and represents time that
present status has been changed as 32bit Binary Number (0hou. 0min. 0.000sec.)
- The MSB (Bit 31) of Fault occurred time is Time-Valid Flag (1:Null)
- 1 : off, 0 : on ⇒ All Status bit
a) SOE Buffer Empty – No SOE Data exists
