CHAPTER 8 - CFW-09 OPTIONS AND ACCESSORIES
Available Functions and Response Times:
In the Modbus RTU protocol specification is defined the functions used for
accessing different types of registers described in the specification. In the
CFW-09 both parameters and basic variables are defined as being holding
type registers (referenced as 4x). In addition to these registers, it is also
possible to access the internal controlling and monitoring bits directly
(referenced as 0x).
Following services (or functions) are available in the CFW-09 frequency inver-
ter for accessing these registers:
Read Coils
Description: reading of internal register blocks or coils.
Function code: 01.
Broadcast: not supported.
Response time: 5 to 10 ms.
Read Holding Registers
Description: reading of register blocks of holding type.
Function code: 03.
Broadcast: not supported.
Response time: 5 to 10 ms.
Write Single Coil
Description: writing in a single internal bit or coil.
Function code: 05.
Broadcast: supported.
Response time: 5 to 10 ms.
Write Single Register
Description: writing in a single register of holding type.
Function code: 06.
Broadcast: supported.
Response time: 5 to 10 ms.
Write Multiple Coils
Description: writing in internal bit blocks or coils.
Function code: 15.
Broadcast: supported.
Response time: 5 to 10 ms.
Write Multiple Registers
Description: writing in register blocks of holding type.
Function code: 16.
Broadcast: supported.
Response time: 10 to 20 ms for each written register.
Read Device Identification
Description: Identification of the inverter model.
Function code: 43.
Broadcast: not supported.
Response time: 5 a 10 ms.
Note: The Modbus RTU network slaves are addressed from 1 to 247. Master
uses address 0 to send messages that are common to all slaves (broadcast).
Data Addressing and Offset:
The CFW-09 data addressing is realized with an offset equal to zero that
means that the address number is equal to the register number. The parameters
are available from address 0 (zero) on, whilst the basic variables are available
from address 5000 on. In same way, the status bits are made available from
