Figure 50: Simulation of the bandwidth distribution in the 32Mbit Flex telegram.
The data size in bytes of each device on the link and the timebase of the data acquisition
on the link (in µs) is needed for the calculation.
The values can be entered manually or retrieved automatically from the current configu-
ration either by clicking the button <Estimate values from current configuration> or by
selecting the corresponding link of the ibaFOB card in the module tree.
The devices in the Flex ring and the corresponding data sizes are listed in the table on
the left. Address 0 is reserved for the Ethernet channel and is not editable.
The "Flex frame utilisation" section shows how much bandwidth is still available. The
color of the section changes with the utilization rate.
Green: OK
Orange: bandwidth for the Ethernet channel < 3 kB/s
Red: too much data
The data values obtained automatically are estimated first. When the configuration is
applied by clicking <OK> or <Apply>, the actual data sizes are shown on the "Info" tab.
If too much data is configured, you can either reduce the number of signals to be meas-
ured or increase the timebase.
Simulating the load
Even when no devices have been connected and configured, the calculation of the tele-
gram size can be used for calculating the expected data load in advance.
Open the I/O Manager in ibaPDA, click on the link of the card and select the "Configura-
tion" tab.
