Communication profiles
When communicating via the plug-in fieldbus adapter, the
ACH550 supports multiple profiles for control and status
information. The ACH550 detects automatically which
communication profile is used by the plug-in fieldbus adapter.
• ABB DRIVES (Vendor Specific) - The ABB Drives Profile
standardizes the control interface among ABB drives. This
profile is based on the PROFIBUS interface. It is discussed in
detail in section
• GENERIC DRIVE (Drive Profile) - The Generic Drive Profile
provides the means to fulfil the drive profile for each fieldbus
type according to its international standard. Examples of
such drive profiles are:
- PROFIdrive for PROFIBUS,
- AC/DC Drive for DeviceNet,
- DRIVECOM for InterBus etc.
The Generic Drive Profile interface is discussed in detail in
section Generic Drive Profile
ABB Drives Profile
The ACH550 supports a virtual data set interface supporting two
data sets, one in each direction. Each data set consists of three
16-bit words called data words. The meaning and scaling of the
data words are fixed.
The mapping of the data words to the process data is realized
with the parameters in
the values 1 to 6 as shown in the table below. However, certain
fieldbus protocols (like PROFIBUS) have a fixed allocation for
data words 1, 2, 4 and 5. Refer to the fieldbus user's manual for
a detailed description of the mapping of process data.
