System integration
As far as no special relation to a PC board is necessary the ibaFOB-4i / -4o and/or iba-
FOB-io are referred to as ibaFOB card. It is assumed that the card(s) run in iba FOB-M
mode (controlled by software application)
ibaPADU-8-M devices are interconnected in a ring structure with the ibaFOB serving as
a central controller for all connected devices. An ibaFOB card can control one (ibaFOB-
io) or 4 fiber-optic links (ibaFOB-4i / -4o). Each link on the ibaFOB card has a TX/RX
port for transmission of control signals and reception of data from connected ibaPADU-
8-M devices. All devices connected in each fiber-optic link must have unique ad-
dresses.
The TX port on an individual
ibaFOB interface must be
connected to the RX port on
the first ibaPADU-8-M in the
fiber-optic ring. Installed de-
vices may be interconnected
in any order (consecutive
addresses are not required)
provided that all devices
have unique address set-
tings. The TX port on the
last device in the chain must
be connected to the RX port
on the respective ibaFOB in-
terface card.
Ring topology
Device addresses are set using the address switch settings on the front panel of the
device. See chapter 7.2 “Device view, interfaces and operating elements” for further
details.
Each device in a chain must have its unique address (0…95).
Important note
This ring topology is only supported by ibaLogic-V3, since numbering of the devices
can be done automatically in ibaLogic-V3.
