Frame time
Fixed cycle time the data frames are being sent. (Smallest configured timebase or
100 µs, when this timebase is an integer multiple of 100 µs. The timebase of all de-
vices must be a multiple of the smallest timebase.)

The table shows the cycle time and the data size of the respective channel:

8.1.6.1 Mirror mode with 32Mbit Flex
The option “mirror mode” is available in ibaPDA version 6.32.0 or higher. The mirror mode
allows multiple ibaPDA systems to acquire simultaneously the data of the same Flex
devices. For this purpose, one ibaPDA system is configured as master. The master sys-
tem is the only one that can configure the Flex devices. The other ibaPDA systems are
configured as slaves and can only acquire the data of the Flex devices, but not change
the configuration.
The master ibaPDA system requires a bidirectional fiber optic connection to receive and
send data to the Flex devices. The slave ibaPDA only needs a single fiber optic connec-
tion to receive data from the Flex devices and the device configuration.
Note
The slave system cannot output data via fiber optics.
Possible connections
Figure 20: Mirror mode connection with ibaFOB-4o-D
The data from the master is mirrored via an ibaFOB-4o-D output board, which is con-
nected to the white connector of the ibaFOB-2io-D for mirror mode. See also chap. 5.6.
The slave ibaPDA receives the data via an ibaFOB-D input board.
