System topologies and addressing

All ibaPADU devices are normally connected in a straight line topology to their respec-
tive ibaFOB-cards. In case of using the external synchronization function (ibaPADU-8
only) the devices are linked in a ring topology. The outputs of the devices are to be
connected with the input of the following devices until all devices are interconnected
and the last device is connected to the ibaFOB-card. All addresses (1...8) within a
chain must be unique.
7.1

Addressing

One address represents 8 analog +8 digital channels. Therefore devices which hold
16 A+16 D channels need two addresses, an ibaPADU-32 needs four addresses re-
spectively.
Hence, you may connect chains of:
 8 ibaPADU-8 or
 4 ibaPADU-16 or
 2 ibaPADU-32
with 1 fiber optic link.
It is permitted to combine different ibaPADU devices in one chain.
Note
Cascading ibaPADU-16, ibaPADU-32 or ibaPADU-32-R is allowed with serial num-
bers 1000 or higher of these devices (3Mbit telegram).
ibaPADU-16, ibaPADU-32 and ibaPADU-32-R devices with serial numbers 1000 or
higher cannot be connected to ibaCom-PCMCIA or ibaFOB x/4 cards (ISA). ibaPADU
devices with S/N <1000 cannot be operated with ibaFOB-io-X cards because these
cards do not support the 2Mbit protocol.
In ibaPDA the card type ibaFOB is not allowed for ibaPADU-16, ibaPADU-32 and
ibaPADU-32-R devices with serial numbers 1000 or higher.
