9.7 Parameter management
ćć 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 .
