Process Data Interfaces
4 FB1111 Piggyback Controller Board
3 Process Data Interfaces
The Process Data Interface is used to communicate with external hardware. The printed circuit board
of the FB1111 supports three different PDI configurations. Thus the FB1111-0142 can be converted
into the FB1111-0140 and FB1111-0141 by replacing resistors in the PDI Configuration Area. As the
EL9820 Evaluation Kit contains the EL9803 adapter board, manual modification of the FB1111-0142 is
unnecessary. Using the EL9803, the SPI and µ-Controller interfaces can be realized without modifying
the FB1111-0142 piggyback controller board. Anyhow for in system testing manual modification of the
PDI Configuration Area may be necessary. Therefore in chapter 0 resistor mapping is listed. Accord-
ing to this mapping the signal pinout on the process data interface connector is shown in chapter 3.3.
Table 3 gives an overview about the FB1111-014X and EL9803 combinations. In chapter 5 detailed
information about the usage of the EL9803 in combination with the FB1111-0142 piggyback controller
board is given.

The Process Data Interface can be changed by reprogramming the EtherCAT configuration EEPROM
using TwinCAT.
3.1 PDI Configuration
Table 4 and Table 5 are showing the resistor and resistor network configuration for the different PDI
interfaces. Additionally to the designator (first column) the value (second column) and the footprint of
the desired resistor (third column) are listed. In the follow
ing columns a “X” is set, if the associated
resistor has to be placed on the PCB.

Note
Usage of the EL9803 adaptor board becomes obsolete, if the FB1111-014X is
used in combination with the EL9800_4A evaluation board.
