The ibaFOB-TDCexp card couples the iba Process Data Acquisition system ibaPDA with

the Siemens control system SIMATIC TDC. To achieve this, the ibaFOB-TDCexp card

must be connected to one of the free ports of the CP52IO (GDM Interface Module of the

SIMATIC TDC).

The CP52IO realizes the access to the GDM memory card CP52M0. Using a fiber optic

link the TDC racks are connected to the CP52IO via the CP52A0 card. Up to 44 TDC

racks can be connected to the GDM in total. For the TDC system, the ibaPDA PC with

an ibaFOB-TDCexp card acts like a TDC rack, the ibaFOB-TDCexp card acts like a

CP52A0 card.

This topology enables the ibaPDA system with an ibaFOB-TDCexp card to communicate

notionally with every processor in one of the connected TDC racks (max. 43).
