IBA ibaCom-L2B-8-8 PROFIBUS Interface PCI Board

Product properties

The ibaCom-L2B-x-8 cards are communication cards which are used to connect stan-dard

 PC PROFIBUS master devices such as Simatic CPUs and CPs. The ibaCom-L2B-x-8 boards

are the successors of the L2B x-8-F PROFIBUS boards.

As far as this description does not refer explicitly to an ibaCom-L2B-4-8 or ibaCom-L2B-8-8.

 the two boards are referred to as ibaL2B boards or cards

The ibaL2B card is, unlike most iba communication interfaces, a copper based inter-face

which holds 4 or 8 so called Profibus DP slaves.

The L2B features the followingfunctionality.

Compliant PCI V2.2 (5 V) board, needs one PCI-slot, Plug & Play functionality

I 1 Mbyte of PCI dual port ram for PC access

Standard PROFIBUS DP slave processors (SPC3)

No configuration jumpers or switches - fully software controlled

Firmware control in the PC without uninstalling the card

Dynamic reassigning of interrupt sources and interrupt generation (board and driversynchronization)

O Up to 4 ibaL2B boards can run in the same PC at the same time (board ids #0.. #3)4 DP slaves

on one PROFIBUS line (ibaL2B-4-8) or 2x4 DP slaves on 2 PROFI-BUS DP lines (ibaL2B-8-8-PCI)

O Each PROFIBUS-link has its own processor which controls and manages the fourslave-processors

ibaL2B supports DP multi master mode that means, that on one PROFIBUS lineseveral masters can

be present each controlling their corresponding slaves (onemaster for one slave only !)

For each slave (each slave represents an iba module which consists of 32 analogplus 32 binary signals)

the following telegram modes can be chosen:Integer

Real

S7-Real (Note in this mode there are only 28 Real values instead of the 32 nor-mally found)

QDA-Flatness (special mode for connection to Siemens flatness measurementsystems).

S7-Request

Each slave may send and receive data simultaneously (same telegram mode forboth directions)

LEDs for each PROFIBUS-line for CPU active (green), PROFIBUS-line o.k. (yel-low), internal error (red)

O 7-segment display for board id and synchronization status

Baud rates up to 12 Mbaud

Automatic baud rate detection

Profibus termination resistors for each PROFIBUS-line (switch)

100% compatibility to its predecessors on the PROFIBUS side (GSD data)
