Send multiple SDI-12 requests

Use

Some serial sensors provide a long list of measurement data that need to be requested by multiple SDI-12 commands, i.e., M1!, M2!, M3!,...

Implementation

Multiple SDI-12 requests are implemented by adding _M1, _M2, _M3, etc. to the S-ADD field of the measurement table. The corresponding D! commands are sent automatically. by the MRL-6.1.

NOTE  The M0! command is run by default and does not need to be added. Hence, for empty S-ADD fields _M0 is assumed.

The same principle can be applied to the R! and C! commands.
