DO I/O data
The set points to the Axis and also the actual from
the Axis are transferred as DO I/O data. The DO I/O
data is transferred using the cyclic data exchange.
Therepresentation of data shall be in big endian format.
The following advantages are obtained due to the telegram
configuring and normalization.
•
Interoperability and interchangeability of PROFIdrive
Controllers and Drive Objects
•
Standard components may be simply commissioned
•
Automation mechanisms in the controller application
Signals
A series of signals with appropriate signal numbers is defined
to configure the DO I/O Data (set points, actual values).
The following values are permissible for the signal numbers.
•
0 = not assigned
•
1-99 = standard signal numbers (profile-specific signal
numbers)
•
100-65535 = signal numbers (device-specific)
The PowerXL PROFIBUS optional card, the defined signal
numbers are listed in the following.

1 Control word 1 STW1 16
2 Status word 1 ZSW1 16
5 Speed set point A NSOLL_A 16
6 Speed actual value A NIST_A 16
Standard telegram 1
Standard telegrams 1 is defined for speed set point
interface operations application class (AC1). The standard
telegrams are selected when configuring the DO I/O Data.
The standard telegram 1 has the following structure.
•
n set interface, 16 bit
