Device properties are stored in the system and read by the driver when it loads, and then the device is programmed according to these loaded values. The properties are protected during read and write access times, and some of them are pre-defined by the configuration dialog box. Different device's functions are influenced by different properties. These properties are represented by an ID code for an application that calls Advantech API functions. An application can use a default value set by the configuration dialog box, or call Advantech API functions: DRV_DeviceGetProperty and DRV_DeviceSetProperty , to modify individual properties in running time.
PCI-1760 supports the following properties:
| Property | Description |
| CFG_BoardID | gets the board ID of the device. |
| CFG_BaseAddress | gets the base address of the currently installed PCI-1760 |
| CFG_Interrupt | gets the IRQ of the currently installed PCI-1760. |
| CFG_BusNumber | gets bus number of the currently installed PCI-1760. |
| CFG_SlotNumber | gets the slot number of the currently installed PCI-1760. |
| CFG_DiChannelCount | gets the digital input channel count. |
| CFG_DiPortCount | gets the digital input port counte. |
| CFG_DoChannelCount | gets the digital output channel count. |
| CFG_DoPortCount | gets the digital output port count. |
| CFG_DiPatternMatchEnabledChannel | gets or sets DI channel which issue interrupt when DI pattern match with preset value. |
| CFG_DiPatternMatchValue | gets or sets DI pattern match value. |
| CFG_DiFilterEnable | gets or sets all of the DI filter enabled status. |
| CFG_DiFilterHiValue | gets or sets an effective period that the signal must last for, otherwise the signal will be filtered out as noise. |
| CFG_DiFilterLowValue | gets or sets an effective period that the signal must last for, otherwise the signal will be filtered out as noise. |
| CFG_DiStatusChangeOnRisingEdge | gets or sets Di channels that issue interrupt on rising edge with status changing. |
| CFG_DiStatusChangeOnFallingEdge | gets or sets Di channels that issue interrupt on falling edge with status changing. |
| CFG_DiCounterEnable | gets or sets DI counter function’s status. |
| CFG_DiCounterMatchEnable | gets or sets the DI counter match function’s status. |
| CFG_DiCounterTrigEdge | gets or sets the time when the DI counter issue interrupt, on falling trigger edge or on rising edge. |
| CFG_DiCounterPreset | gets or sets DI counter preset value. | CFG_DiCounterValue | gets or sets DI Counter’s matching value. When the counter’s value equal this value, the device will issue a interrupte. |
| CFG_DiCounterOverflow | gets or sets DI counter overflow interrupt function’s status. |
| CFG_DiCounterDirection | gets or sets the Counter up/down counting setting. |
