1Introduction
The boards ibaFOB-io-PCI, ibaFOB-io-S, ibaFOB-4i-PCI, ibaFOB-4i-S, ibaFOB-4o and
ibaFOB-OF-Link are fiber optic communication cards which are used to connect a stan-
dard PC to the iba peripheral devices such as ibaPADUs, ibaNet750-BM devices and
ibaLink signal modules (SM).
As far as the following text does not refer to a particular card, the boards are referred to
as ibaFOB boards.
The unique peripheral I/O concept based on the ibaFOB boards, features characteristics
otherwise unknown on standardized field buses such as:
Full deterministic transmission profiles for all fiber optic buses and connected devices
(1ms).
Internal and/or external synchronization on the bus, even for more than one bus with
programmable cycle times between 1.0 and 9.9 ms in steps of 100 μs.
Deviation less than 2 μs between several busses (external synchronization)
The iba fiber optic transmission standard integrates not only A/D converters (ibaPADU)
but a huge variety of PLC interfaces and hence allows the realization of heterogene-
ous measuring and I/O topologies. The following devices can be connected:
ibaFOB x/4 (ISA)
ibaFOB x/4-F (ISA) with ibaFOB-OF-Link
ibaFOB 2/2 I/O (ISA)
ibaLink-SM-64-io (Siemens Simatic S5 115U, 135U 155U; MMC216 all types)
ibaLink-SM-128V-i-2o (VME32 & VME64 rack)
ibaNet750-BM (Wago IO system 750)
ibaBM-FOX-i-3o (FO-splitter and repeater)
ibaPADU-8, ibaPADU-8-ICP, ibaPADU-8-M, ibaPDAU-8-S, ibaPADU-16, ibaPADU-
32-T, ibaPADU-32-R and ibaPADU-8-O (A/D & D/A -converter)
ibaBM-SLM (Simolink Monitor for Siemens Motion Link Bus)
ibaBM-DDCSM (Monitor for ABB DDCS+ Drivebus)
Adjustable bus timing (ring topology in combination with ibaLogic only!)
Easy handling without the termination problems of copper based systems
The integration in hazardous areas is no problem in terms of EMI due to the fiber
optic communication concept.
One source can be accessed by multiple clients at the same time by just multiply-
ing the optical fibers (ibaFOx-3 and ibaFOB-OF-Link splitting devices) – so I/O pe-
ripherals may be used for process control and measuring at the same time. This
also makes redundant structures easy.
100% compatibility to its predecessors based on the ISA bus
