S475 slave can't display data on cloud platform

[Question]: RS485 slave device is mapped on S475, and slave data can be read in the slave mapping table of configuration software, but data points are not connected on cloud platform.
[Solution]: If mapping numeric data, use the "03" function code; if mapping Boolean data, use the "01" function code, which is determined by the register address mapped in S475. Details of this introduction can be found in Appendix C of the Instructions.
