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.
Table 112. PROFIBUS Option Card
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
