Process Data Interfaces
8 FB1111 Piggyback Controller Board
3.4 Using the FB1111-0142 in SPI- or µC-Mode
The FB1111-0142 supplies all process data signals of the ET1100 on its PDI connector. Therefore the
FB1111-0142 can be configured to operate in SPI- or µC-Mode. In these cases the pinout of the
FB1111-0142 differs from the other piggyback controller board variants. The following table (Table 7)
shows the signal definitions on the FB1111-0142s PDI connector.
