The easiest way to define the bus parameters is to let the system calculate them. You
only have to set:
– the node address,
– the baudrate and
– the line redundancy mode
to the required values. All other parameters don’t need to be changed. The
Parameters marked with a * in Table 3 are calculated automatically during
download depending on the actual configuration for the slave units.
The automatic calculation ensures that all calculated parameters will be on the safe
side. This means also manual changes have to be considered. Therefore no changes
of the actual settings in direction to faster but insecure values takes place.
To get the optimized values for the PROFIBUS master parameters set the
parameter Calculation method to Minimum value based. The automatic
calculation will now recalculate all parameters. The result is the fastest possible
cycle time you can reach for the configured slaves.
If you have devices that need special settings then first proceed as described
above. In a second run do the manual adjustments to the specific parameters,
switch the parameter Calculation method to Actual value based and repeat
automatic calculation.
