[Problem]: Customer uses S275 to connect the slave device but cannot read the value on the cloud platform.

[Solution]: 

  For example, if the slave device function code is 03 , 

                     the starting address of mapping is 0, 

                     the number of registers is 2, and the Master device starting address of mapping is 2000, 

       The register address set on cloud platform should be 2000/20001, not 0/1.

It is confirmed that on the cloud platform customer sets the register address according to the local machine, and does not fill in the mapping address to S275.
