The contents represented by the register in bits are: switch value, alarm information,
etc.
Register read and write in word units
•
Function codes 03、04 are used to read multiple word-type registers
•
Function code 06 is used to write single word-type registers
•
Function code 16 is used to multiple word-type registers
The content of the word-type registers can be voltage, current, generated energy, etc

0x0231 561 Channel arc alarm status This bit is set when the channel arc strength is above the alarm
threshold. Clear the alarm and set it to 0.
0x0232 562 Bus voltage too low alarm
status This bit is set when the bus voltage is below the alarm
threshold. Cleared below the alarm release threshold
0x0233 563 Bus voltage to high alarm
status This bit is set when the bus voltage exceeds the alarm
threshold. Cleared below the alarm release threshold
0x0234 564 Temperature sensor 1
high temperature alarm
status This bit is set when the temperature sensor 1 temperature
exceeds the alarm threshold. Cleared below the alarm release
threshold
0x0235 565 Temperature sensor 2
high temperature alarm
status This bit is set when the temperature sensor 2 temperature
exceeds the alarm threshold. Cleared below the alarm release
threshold
0x0236 566 Channel reverse current When the reverse current is generated in the channel, the
