The part "Diagnostic counters" is not available for all boards.

Interface settings

"In use" check box

If the RM interface board should be used by ibaPDA, you must check this box.

This is, for example, necessary if ibaPDA and ibaLogic are active in a hybrid configuration on the PC, with each application having to use its own boards. One board must only be used by one application.

Swap mode

Select the appropriate swap mode from the drop-down list in this field. The drop-down list provides several options of high- and low byte swapping (Endian Control). Which swap mode is suitable for your configuration depends on the connected source system. Changes in this setting have immediate effect unless acquisition is running. If the acquisition is running at this time, the changing applies only after pressing <OK> or <Apply>. The acquisition is then stopped and restarted.

This setting is disabled with recent boards such as PCI 5565PIORC. You can select the swap mode in the settings of the data module, see Reflective Memory – General tab .

Memory length limit

This parameter describes the size of the mapped memory space. You should adjust the memory size according to your needs, either by means of the up/down arrows or by entering a value. Reduce the size if you do not need that much memory length. This will save memory space in the ibaPDA computer.

Node ID

This is the node ID as set on the RM interface board in the ibaPDA computer. It is for display only and cannot be altered here.

Network address offset

This optional setting is only available if a card of VMIC 5576 type is used. The exact setting of a network address offset is required if a 256 kB or a 512 kB card is used in a 1 MB ring.

Check that offsets are on 4-byte limits

Usually, the checking of the 4-byte limits is selected by default in order to guarantee a data addressing without gaps. Data of 4-byte size (DINT, DWORD, FLOAT) must always be addressed on a 4-byte offset, relative to the start address. If not, an error message will be generated and the configuration is not valid.

When addressing data, otherwise than on 4-byte limits, be sure to disable this option in order to suppress error messages.

Force 4-byte limit alignment for digital signals

If this option is enabled, it makes sure that the data is always read along 4-byte limits. This is done to prevent sending of wrong data by some Reflective Memory boards if not reading exactly along 4-byte boundaries.

This option is enabled by default when a 5565PIORC board is used.
