IBA ibaFOB-2io-X PCI Interface Board with High Data Transmission Rate

Introduction

The board ibaFOB-2io-X is a fiber optic communication card like the other well-known

boards ibaFOB-io-PCI, ibaFOB-io-S, ibaFOB-4i-PCI, ibaFOB-4i-S, ibaFOB-4o and iba

FOB-OF-Link which are used to connect a standard PC to the iba peripheral devices

such as ibaPADUs, ibaNet750 devices and ibaLink signal modules (SM).

The essential difference to the boards without the "X" in the name is a higher data trans

mission rate on the fiber optic link. Of course, in order to take advantage of this enhanced

data rate there should be the appropriate peripheral devices installed which support the

high data rate too. On one hand these are devices from iba which care the "X" in the

name and on the other hand system components of other manufacturers like ABB AC

800 PEC or Simatic TDC with LO5A interface.

As far as the following text does not refer to a particular card, the boards are referred to

as ibaFOB boards.

The ibaFOB I/O Concept

The unique peripheral I/O concept based on the ibaFOB boards, features characteristics

otherwise unknown on standardized field busses such as:

 Full deterministic transmission profiles for all fiber optic buses and connected devices

(1 ms).

 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 cards incl. ibaFOB x/4-F (ISA) and ibaFOB-OF-Link

 ibaLink-SM-64-io (Siemens Simatic S5 115U, 135U 155U; MMC216 all types)

 ibaLink-SM-128V-i-2o (VME32 & VME64 rack)

 ibaNet750 (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-16-M-2. ibaPADU-32-T, ibaPADU-32-R and ibaPADU-8-O

 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 (ibaBM-FOX-i-3o and ibaFOB-OF-Link splitting devices) – so

I/O peripherals may be used for process control and measuring at the same time.

This also makes redundant structures easy.

What's new?

The ibaFOB-2io-X and respectively the ibaFOB-4i-X and ibaFOB-2i-X card represent the

new generation of iba's fiber optic PC boards. These boards extend the existing board

family and will replace the previous ibaFOB-cards in long-term. The new boards are

100% compatible on the fiber optical bus side while in the PC the interface and dual port

ram layout differ between the old and new boards.

The new cards features are:

 Full Plug&Play functionality.

 Three different data transmission rates per optical link:

3.3 Mbit/s, 5 Mbit/s and 32 Mbit/s

The 2 MBit data transfer to the old ibaPADU-16. - 32 devices is not supported.

(All ibaPADU-16 and -32 with serial number 999 and below use 2 Mbit data

transfer.)

 Three modes of operation on each fiber optic link:

 F-mode, for data acquisition and output up to 1 kHz (1 ms cycle) with 3.3 Mbit/s

 M-mode, for data acquisition up to 25 kHz (40 μs cycle) with 5 Mbit/s

 X-mode, for data acquisition up to 20 kHz (50 μs cycle) with 32 Mbit/s

 Enhanced card diagnostics and card information in ibaPDA-V6
