Cycle times in the 32Mbit Flex ring topology
Exemplary device configuration in the Flex ring topology
ibaPDA automatically detects the devices in the Flex ring topology and determines the
max. possible sampling rate, depending on the type and the number of devices.
The devices in the ring topology are addressed via the rotary switch for the device ad-
dress.
The individual devices in the ring can work with different cycle times. However, these
cycle times have to be an integer multiple of the smallest cycle. Example: Device #1
works at a cycle of 0.5 ms, device #2 with 1 ms, device #3 with 4 ms, etc. If the maximum
data rate has been exceeded, ibaPDA issues an error message with the indication that
the timebase has to be increased or the data amount has to be lowered.
The calculation of the maximum data amount depends on the fastest device in the ring
topology. This means: If you increase the cycle time of slow devices in the ring topology,
this does not mean that a higher amount of data can be transferred. Only if you increase
the cycle time of the fastest device, also the data amount can be increased.

11.2 ibaFOB-D Network
Beginning with ibaPDA version 6.26.0 or higher, an ibaFOB-D network adapter will be
optionally installed.
Optionally, the installation of the driver can also be disabled in the installation wizard. For
an individual installation the file ibaFobDNetworkInstall.exe is available. You find the file
