ibaPADU-8/ -16/ -32/ -32-R
Up to 8 devices in a line
structure.
Every device with 8 analog +
8 digital channels must be set
to a unique station address
between 1...8.
If 2 devices carry the same
address the subsequent de-
vice in the fiber optic link
overwrites the content of the
previous device.
The image, left, shows the
principle of the data pack-
ages in an ibaFOB-telegram.
Each box contains 8 analog +
8 digital signals. The device
address determines where
the data are placed in the te-
legram. Therefore, the posi-
tion of a device in the chain is
independent of the address
setting.
2 devices in a line structure.
The device addresses are to
be set as follows.
Because every device needs
four addresses the settings
#1 and #5 are correct only in
order to use all signals of
both devices!
