APCI-3xxx Functions of the board 8 FUNCTIONS OF THE BOARD 8.1 Block diagram Fig. 8-1: Block diagram: APCI-3010 and APCI-3016 Fig. 8-2: Block diagram: APCI-3110 and APCI-3116 8.2 Analog inputs There are 16 analog input channels on the boards – the resolution of the APCI-3010 and APCI-3110 is 12-bit and of the APCI-3016 and APCI-3116 16-bit.
Functions of the board APCI-3xxx 8.2.1 Overview Up to 16 analog Single Ended or up to 8 analog differential signals can be connected to the board. After the signals are transferred over a filter (RC-component) to a multiplexer (time multiplexed system), they are lead over a programmable instrumental gain to a 16-bit A/D converter (or 12-bit for APCI-3010 and APCI-3110). Data acquisition with the APCI-3xxx is based on a time-multiplex system.
APCI-3xxx Functions of the board Please note: During the switching of the voltage range from unipolar to bipolar or from bipolar to unipolar there is a longer settling time of the measuring chain. 8.2.3 Analog input switch (differential inputs) The input impedance is the input resistance (1012 Ω) of the PGA and the connected capacities (C1 and C2). Input impedance= 1012 Ω || 5 nF Fig. 8-3: Analog input switch (differential) *R Strom = optional component part for the version current.
Functions of the board 1) APCI-3xxx Simple mode The software initializes and starts the A/D conversion and after this step it reads the digital value of one or more channels.
APCI-3xxx Functions of the board b) Single hardware triggered scan This scan can be triggered with rising or falling edge (software initializes it).
Functions of the board APCI-3xxx d) Continuous software scan with timer delay e) Continuous hardware triggered scan Note: In this scan mode the external signal triggers only one scan at a time! f) Continuous hardware triggered scan with timer delay 32
APCI-3xxx 3) Functions of the board Sequence modes (with DMA) There are 2 sequence modes that are shown in the following two examples: a) Simple sequence mode (example 1 and 2) b) Sequence mode with delay (example 1 and 2) Note: The sequence mode always uses DMA! a) Simple sequence mode Simple sequence mode – Example 1 In this example the interrupt occurs at the end of each sequence (after 5 acquisitions) and the acquisition is stopped after 3 sequences.
Functions of the board APCI-3xxx dw_NbrOfChannel =5 dw_SequenceChannelArray = 0, 1, 2, 3, 4 b_DelayTimeMode = ADDIDATAG_DELAY_NOT_USED dw_SequenceCounter =0 dw_InterruptSequenceCounter= 2 b) Sequence mode with delay Sequence mode with delay - example 1 The interrupt occurs after the second sequence (10 acquisitions) and the acquisition is stopped. The total delay time from the start of one sequence to the next one is 100 µs.
APCI-3xxx Functions of the board dw_DelayTime = 20 dw_SequenceCounter = 2 dw_InterruptSequenceCounter= 2 4) Auto refresh mode The analog acquisition is initialized and writes the values of the channels into a storage location on the APCI-3xxx. The PC reads the data asynchronous to the acquisition. 8.3 Analog outputs There are 4 analog output channels with a resolution of 12-bit and a precision of 11-bit on the APCI-3110 and APCI-3116.
Functions of the board APCI-3xxx Fig. 8-4: Reaction time of the analog outputs When the computer is switched on, the analog outputs are temporarily in an undefined state. It is thus essential that the computer is switched on before the connected peripherals. After the Power ON reset of the computer, a voltage of 0 V is applied to all analog outputs. Fig.
APCI-3xxx 8.4 Functions of the board Digital inputs The inputs are designed for the acquisition of external signal states: The input information is loaded as numerical value into a memory unit of the PC by software. This numeric value calculates the state of the inputs signals. 24 V optically isolated inputs They correspond to the 24 V industrial standard (IEC1131-2): - logic"1" corresponds to an input voltage superior to 19 V - logic"0" corresponds to an input voltage inferior to 14V.
Functions of the board 8.5 APCI-3xxx Digital outputs The APCI-3xxx has 4 optically isolated outputs. The positive logic is applied: - logic"1": Sets the output by software. - logic"0": Resets the output. NOTICE! The supply unit for the external voltage supply of the board must supply the power that is needed for your application. The max. supply voltage is 35 V. For each output a current of 50 mA can be set.
APCI-3xxx 8.6 Functions of the board TTL inputs and outputs The board APCI-3xxx has 24 TTL channels that are divided into three ports: Table 8-1: TTL I/O (ports) Port Description Channel Port 0 Output Channel 0-7 Port 1 Input Channel 8-15 Port 2 Programmable I/O Channel 16-23 Fig. 8-8: Block diagram of the TTL I/O 8.7 Watchdog A 16-bit watchdog is available for the analog outputs and for the 24 V outputs. After its reload value (timeout) the watchdog resets the outputs.
Functions of the board 8.8 APCI-3xxx Timer The 16-bit timer is a downwards counter that can generate an interrupt after the reload value (timeout). With the timer a time base is provided independent from the PC clock, with which for example operations can be synchronized. The status of the counter value and of the reload value as well as the status and interrupt register can be read back through software. The operation states can be read back.
APCI-3xxx Functions of the board Upward counter Fig. 8-9: Run down of the upward counter After reaching the reload value, the counting value is set on 0 and continues to be counted. At an overflow an interrupt can be generated. Downward counter Fig. 8-10: Run down of the downward counter In order to get the same counting value as in the upwards mode, the reload value must be set on 3. The counter counts down to 0 and will be reset to the reload value from the next edge cycle on.
Functions of the board APCI-3xxx 8.10 Setting a digital output At the run down of the counter/timer/watchdog a digital output (24 V) can be set. Here also the output level can be defined. The output will be enabled for an (input) clock. Fig.
