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 following
functionality.
Compliant PCI V2.2 (5 V) board, needs one PCI-slot, Plug & Play functionality
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 driver
synchronization)
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)
Each PROFIBUS-link has its own processor which controls and manages the four
slave-processors.
ibaL2B supports DP multi master mode that means, that on one PROFIBUS line
several masters can be present each controlling their corresponding slaves (one
master for one slave only !)
For each slave (each slave represents an iba module which consists of 32 analog
plus 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 measurement
systems).
S7-Request
