Bus Parameters Tab
The Bus Parameters tab contains the parameters for the communication on the PROFIBUS net-
work. The Bus Parameters tab is shown below.
The Bus Parameters are a number of settings which define the communication behavior and timing
on the PROFIBUS network. The Bus Parameters depend on the selected baud rate, certain slave
communication parameters as well as the number of I/O data bytes exchanged between the Master
Unit and each of the slave devices.
The required combination of Bus Parameters is calculated by the program, based on the dependen-
cies mentioned above. However, the user can change selected Bus Parameter manually if the appli-
cation requires this.
Precautions for Correct Use Precautions for Correct Use
Changing the calculated Bus Parameters manually is not recommended and should only be per-
formed if this is absolutely necessary. Changing the Bus Parameters to an invalid combination,
may result in Unit malfunctioning and unexpected behavior.
Note When making changes to Bus Parameters, selecting the Optimize buttons allows toggling
between the optimized values and the changed values. Selecting another baud rate after
changing parameters will reset the Bus Parameters to default values for the new baud rate.
The table below lists the parameters, shown in the Bus Parameter tab.
