ibaFOB-TDCexp

Characteristics

5.2
The card has the following characteristics:
 PCI Express card for 1.0-x1 compatible slot
 100 % functional compatible with the predecessor ibaFOB-TDC
 Firmware update without dismounting the card
 Bidirectional fiber optic link with 640 Mbit/s
 Absolutely noise free acquisition of process data
 Enhanced SIMATIC TDC system diagnostics
 Display for card id, processor and link status via 7-segment display and LEDs
 Up to 4 PCIe cards per PC
 Plug and play installation
 All component parameters are 100% controlled by software. No wiring or jumpering
is necessary for that card.

Operational modes

5.3
To measure SIMATIC TDC system numeric and binary values must be transported be-
tween the TDC system and the PC, which means that internal variables of the TDC sys-
tem may be visualized and recorded. For recording purposes two different software pack-
ages are supported by the ibaFOB-TDCexp card:
 SD-TDC-lite:
All values to be measured by ibaPDA have to be manually programmed in CFC
charts of the control unit. Changes of signals require a change in this chart. Up to
16 process telegrams are to be defined per card which transport the values to
ibaPDA containing 32 analog plus 32 digital variables each. Structure and length of
the process telegrams are determined by ibaPDA. Up to 4 cards in a PC are sup-
ported by ibaPDA.
In addition the ibaPDA-Technostring (non-structured ASCII-string with a length of up
to 512 bytes) can be configured.
 SD-TDC-Request:
The definition of the signals to be measured is independent of the connected con-
trol unit system. All changes are done in ibaPDA. ibaPDA supports the functionality
to select the internal TDC variables by their names, i.e. the chart, function block and
the connector names. To do that for every TDC CPU special service function blocks
must be included in the CFC chart of the control unit.
The information about the variable names (address books) is transferred from the
TDC CPU to the ibaPDA system directly via the ibaFOB-TDCexp card.
ibaPDA supports up to 4 cards with up to 50 processor connections per card and
additionally, the ibaPDA-Technostring.
