Function Library 51
_8136_A_Read_Value
This function reads a digital value from ADC channel. . A word can
be read from this function. The mapping value for 0V is 2000,
+10V is 4000 and –10V is 0. There are six channels in one card.
All channels are free to run individually.
_8136_A_Read_Volt
This function reads a voltage value from ADC channel. A voltage
value can be read from this function directly. The range of the
read-back voltage value is for –10.0V to +10.0V. There are six
channels in one card. All channels are free to run individually.
_8136_A_Output_Control
This function will stop the outputting of any voltage from DA chan-
nel, and will immediately close DA channel. It can be open again
by this function too.
_8136_A_Set_Trigger
This function enables/disables DA channel output by trigger
source. The trigger source would be ADC comparator interrupt or
encoder counter comparator interrupt.
_8136_A_Set_Trigger_Map
This function assigns each channel's trigger source. The trigger
source is selected by one parameter. Each bit of this parameter
represents one kind of trigger source. Bit 0-5 means trigger source
is from encoder counter channel 0-5 and bit 8-13 means trigger
source is from ADC channel 0-5. Set 1 is for enabling and 0 is for
disabling.
_8136_A_Set_Preload_Volt
Once user set the DAC trigger function, the preload voltage must
be set . When the trigger is active, the DAC channel will output this
preload value.
_8136_A_Set_Compare_Value
This function is for DAC trigger output or simply for generating
ADC comparator interrupt. When user wants to output a preload
voltage which is triggered by ADC level, the trigger level must be
set by this function. The range is from 0 to 4000.
