What happens if an address higher than 3 is selected in BM-MM?

The BM-HMI only communicates with measurement modules BM-MM at the address 1 to 3, depending on the number of selected modules in the parameter Measurement module at the sub-menu Number of Sets. This way, if one set is selected, BM-HMI will communicate with the BM-MM only at address 1. If two groups are chosen, BM-HMI will establish a connection with the BM-MM at addresses 1 and 2, and so on. In this case, if an address higher than the number of sets is selected, a communication failure will occur in BM-MM.

The address 4 to 31 can be configured to download the log through BM-MM, for example.
