FO connections - ibaFOB

FO connections - safe & reliable

The cards of the ibaFOB-D family are communication cards for ibaNet fi ber optical links. The ibaFOB-D cards can be used for connecting a computer like e.g. iba industrial computers with iba peripherals like e.g. ibaPADU compact measurement modules, ibaLink system couplings and iba bus modules.

At a glance

 ·         PCI express cards for connecting iba fi eld devices and system couplings

 ·         Fast data transfer between card and computer’s memory by DMA technology (CPU load relieving)

 ·         Support for all ibaNet communication protocols (2Mbit, 3Mbit, 5Mbit, 32Mbit and 32Mbit Flex)

 ·         Up to 4060 Byte user data per FO link

 ·         ibaFOB-io-ExpressCard for installation in notebooks

 ·         ibaFOB-io-USB for connection to USB ports

 ·         “Plug and Play“ installation

The ibaFOB-D family

ibaFOB-D cards and ibaFOB-io-USB adapters are available in different versions:

 ·         ibaFOB-D cards: PCI express cards with different numbers of FO connections

 ·         iibaFOB-io-ExpressCard for installation in notebooks; available in 2 different versions for express card/54 - and express card/34 slot.

 ·         ibaFOB-io-USB adapter for connecting to USB ports

Communication protocols

All current and former ibaNet communication protocols are supported by ibaFOB-D cards. The fiber optical input/output channels of one card can detect and process all valid ibaNet protocols independently from each other: 3Mbit, 5Mbit, 32Mbit and 32Mbit Flex.

Using the ibaNet protocol 32Mbit Flex, it is possible to transmit measurement and confi guration data bidirectionally via FO connections with 32 Mbit/s. In contrast to other protocols, a LAN connection for transmitting confi guration data is no longer required. The size of the data telegrams is fl exible and can be up to 4060 Byte per FO connection.

Ring topology with 32Mbit Flex

32Mbit Flex supports up to 15 “fl ex capable” devices connected in a ring topology. The size of the data telegrams is fl exible, as long as the total data amount of 4060 Byte will not be exceeded.

The maximum sampling rate depends on the acquisition devices and can be selected fl exibly from 1 kHz to 100 kHz. The following basically applies: The less data are transferred, the higher is the possible sampling rate.

ibaPDA offers a useful function when setting sampling rate and data amount. For a device connected to the fi ber optics, you can determine in the I/O manager, the maximum data amount that can be transferred depending on the confi gured sampling rate. Thus, you can e.g. estimate the maximum possible number of participants in a ring topology or the amount of data needed for the I/O modules, that are to be used.

Fast data processing with reduced CPU load

Due to the DMA technology (DMA = Direct Memory Access) measured data are written directly into the computer’s memory which is used by the software application for reading the data. This is a signifi cant relief for the CPU load while data traffic is boosted.

Extension modules for output signals

With the extension module ibaFOB-4o-D, 4 outputs are available that can be used for 2 different functions:

 ·         Mirroring the inputs: The optical signals of the input channels are mirrored to the output channels without delay.

 ·         Application outputs in duplex operation: Thus, with ibaPDA the alarm outputs can be used. Hence, in ibaLogic, output resources are available.

For output signals, the ibaFOB-4i-Dexp and ibaFOB-2i-Dexp cards can be extended with up to 2 additional ibaFOB-4o-D modules. You can only connect one additional module for mirroring the inputs and outputs to the ibaFOB-io-Dexp and ibaFOB-2io-Dexp cards.

FO connection to notebooks

There are notebook cards and an USB adapter available for connecting notebooks to an ibaNet FO conductor.

The ibaFOB-io-USB adapter transmits the FO connection to a USB 2.0 or USB 3.x interface.

The USB adapter offers an FO input and an FO output. Performance and function are the same as for an ibaFOB-io-D card.

For one notebook or PC, you can use only one iba- FOB-io-USB adapter.
