The Modbus functional codes supported by V800 are listed below:
Function
Code
(Hexadecimal)
Description of Functions
Read coil status
0x01
Read coil status by digit. Each digit for the controlling character is
mapped to coil 0~15 respectively.
Read discrete input
status
0x02
Read discrete input status. Each digit for the status character is
mapped to coil 0~15 respectively.
Read multiple hold
registers
0x03
Read multiple hold registers. It can read all the application parameters,
status parameters, controlling characters, status characters and
setting values of V800.
Read multiple input
registers
0x04
Read multiple input registers. The address for analog input register
starts from 0x1200.
Enforce single coil
0x05
Perform writing action for a single output digit. Each digit for the
controlling character is mapped to coil 1~16 respectively.
Write to a single hold
register
0x06
Perform writing action for a single hold register. All the parameters,
controlling characters, status characters and setting values of V800
are mapped to the hold register.
Query for the anomaly
status
0x07
Query for the anomaly status information. In V800, the failure
information of the frequency inverter can be queried.
Failure diagnosis
0x08
Execute field diagnosis for the bus failure. Support the sub-codes, like
querying (0x00), rebooting (0x01), monitoring (0x04) and
zero-clearing(0x0A) etc.
Enforce multiple coils
0x0F
Perform writing action for multiple output digits respectively. Each digit
for the controlling character is mapped to coil 1~16 respectively.
Write to multiple hold
registers
0x10
Perform writing action for multiple hold registers. All the parameters,
controlling characters, status characters and setting values of V800
are also mapped to the hold register.
Read/write to multiple
hold registers
0x17
This function equals to combining 0x03 and 0x10 into a new
command.
