ABB ACS880 - Modbus Holding Register Addresses; The Transparent Profile

￭ Modbus holding register addresses
The table below shows the default Modbus holding register addresses for drive data.
This profile provides a converted 16-bit access to the data.
Register data (16-bit words)Register address
Control word. See section Control Word (page 596).
The selection can be changed using parameter 58.101 Data I/O 1.
400001
Reference 1 (REF1).
The selection can be changed using parameter 58.102 Data I/O 2.
400002
Reference 2 (REF2).
The selection can be changed using parameter 58.103 Data I/O 3.

Error code access. See section Error code registers (holding registers
400090…400100) (page 608).

Parameter read/write.
Parameters are mapped to register addresses according to parameter 58.33
Addressing mode.

The Transparent profile
The Transparent profile enables a customizable access to the drive.
The contents of the control word are user-definable. The control word received from the
fieldbus is visible in parameter 6.5 EFB transparent control word, and can be used to
control the drive using pointer parameters and/or application programming.
The status word to be sent to the fieldbus controller is selected by parameter 58.30 EFB
status word transparent source. This can be, for example, the user-configurable status
word in 6.50 User status word 1.
The Transparent profile involves no data conversion of the control or status word.
Whether references or actual values are scaled depends on the setting of parameters
58.26...58.29. The references received from the fieldbus are visible in parameters 3.9
EFB reference 1 and 3.10 EFB reference 2.
The Modbus holding register addresses for the Transparent profile are as with the ABB
Drives profile (see page 559).
