The fault information is consistent with the fault
type serial number in the function code, and what
is fed back to the host computer is the hexadecimal
data value instead of the fault symbol.

9.7 Parameter management
The Modbus master station can obtain the group number and group number value of the system parameter
from the CPU board through the corresponding command, and obtain the group number of the corresponding
group. It is stipulated that the communication function code is "0x03", and the communication address is
defined as in Table 9.5 .
