PROFIBUS-DP can transfer data using two distinct modes. The first of these modes is
cyclic, where signals are sent in predefined blocks at regular intervals. This is the
equivalent of the hard-wired example in Figure 2-1.
The second method of transfer is called non-cyclic data, and is used for sending values
that only need to be changed occasionally or where the source or destination of the
signal changes. This is the equivalent of a temporary patch lead that is removed after
use.
2.2 About SI-PROFIBUS
SI-PROFIBUS is a fieldbus option module that can be installed to the option module
slot(s) in any of the following drives to provide PROFIBUS-DP slave connectivity:
• Unidrive M700/M800
• Unidrive M200/M300/M400 (firmware V01.03.00 or later)
It is possible to use more than one SI-PROFIBUS or a combination of SI-PROFIBUS
and other option modules to add additional functionality such as extended I/O, gateway
functionality, or additional PLC features.
