Swap analog signals

Set the swap mode according to the signal source. You can choose between the following 4 options:

The swap mode to be selected depends on the swap mode of the signal source.

Swap digital signals

Choose here whether the digital signals should be swapped on a 4-byte basis.

• • False: no swap (default)

  • True: byte order changes from access mode - for 16-bit access from AB to BA - for 32-bit access from ABCD to DCBA

Read digital signals

Select, how the digital signals should be fetched. Depending on your selection the swap mode, the addresses and bit numbers in the signal table Digital will be adapted automatically.

• • 16 bit: addresses change in 2-byte steps, bit no. 0...15

  • 32 bit: addresses change in 4-byte steps, bit no. 0...31

DMA mode (only for boards which support DMA, e.g. PCI/PCIE-5565PIORC/ibaFOB-R)

Enable the DMA mode in order to improve performance of the board and reduce the CPU load of the PC.

Asynchronous mode (only for boards which do not support DMA, e.g. PCI-5576)

In asynchronous mode, the data is copied from the card’s memory into the memory of ibaPDA outside of the interrupt service routine (ISR). This mode can be used to measure large data volumes on a slower time base. If you want to activate the asynchronous mode, set this option on TRUE.

Module layout

Number of analog and digital signals

Here, you can increase or decrease the number of signals in the module. By default, 32 signals are preset. You may enter any value between 0 and 1000. The signal tables will be adjusted accordingly.
