Function Code 0x23 is a user defined Modbus function code, which has a format similar to
Function Code 0x03, except for the inclusion of a "repeat count." The repeat count (RC) is used to
indicate that the same N registers should be read RC number of times. (See the Number of
Repeats bullet on page B-14.)
