6.3 Modbus Data Mapping
A “coil” in Modbus is a single-bit binary data item which can be both read and written. In Praxi 100 family AC drives, the
coils refer to some bits in the fieldbus control word. See page 34.
A “discrete input” in Modbus is a single-bit binary data item which is read-only. In Praxi 100 family AC drives, the
discrete inputs refer to the fieldbus status word bits. See Chapter 10.
The Praxi AC drives have trip counters for operation days and energy. These counters can be reset to zero by writing
value ‘1’ to addresses defined in table below. You can also use coils defined in chapter 6.3.1.
