6.3 Modbus data mapping
6.3.1 Coils registers
A "coil" in Modbus is a single-bit binary data item which can be both read and written. In VACON
®
100 family AC drives, the coils refer to some bits in the fieldbus control word." See page 34.
6.3.2 Clearing resettable counters
The VACON
®
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.
6.3.3 Discrete inputs
A "discrete input" in Modbus is a single-bit binary data item which is read-only. In VACON
®
100
family AC drives, the discrete inputs refer to the fieldbus status word bits. See Chapter 10.
