FC101 Design Guide

Modbus telegram. Coil 127 decimal is addressed as coil
007Ehex (126 decimal).
Holding register 40001 is addressed as register 0000 in the
data address eld of the telegram. The function code eld
already species a holding register operation. Therefore,
the 4XXXX reference is implicit. Holding register 40108 is
