Introduction

The board ibaFOB-4i-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.

The ibaFOB-4i-X can be extended by means of the add-on module ibaFOB-4o-X with

four fiber optic output ports in order to get a device with full input-output functionality (e.

g. with ibaLogic).

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

as ibaFOB boards.
