1. Introduction

1.1. General remarks

First of all, we would like to congratulate you to the purchase of a high qualityDEDITEC product.

Our products are being developed by our engineers according to qualityrequirements of high standard. Already during design and development we takecare that our products have -besides quality- a long availability and an optimalflexibility.

Modular design

The modular design of our products reduces the time and the cost of development.Therefor we can offer you high quality products at a competitive price.

Availability

Because of the modular design of our products, we have to redesign only a moduleinstead of the whole product, in case a specific component is no longer available.

1.2. Customer satisfaction

Our philosophy: a content customer will come again. Therefor customersatisfaction is in first place for us.

If by any chance, you are not content with the performance of our product, pleasecontact us by phone or mail immediately.

We take care of the problem.

4.3.8.2. Usage of the VIs in LabVIEW

Some functions of the DELIB-library are expecting a string as a parameter value.

This example shows how to use such functions in LabVIEW.

We will use the A/D converter function which is used to set the voltage range as anexample.

The definition of this function is:void DapiADSetMode(ULONG handle, ULONG ch, ULONG mode);

The voltage ranges for this function are already defined in the DELIB-library.

Example code in C/C++:DapiADSetMode(handle, 0, ADDA_MODE_UNIPOL_5V);

This code can also be written like this:DapiADSetMode(handle, 0, 1);

In the delib.h file can you read the hexadecimal values to determine the modes.The hex values must be convertet to decimal.

After the installation of the DELIB-library, the delib.h file is located in the followingdirectory: C:\Programs\Deditec\DELIB\Include\delib.h

Software |Seite 46

The function could look like this in LabVIEW:

The channel and mode are passed as unsigned long

This command saves the counters of all digital inputs simultaneously into atemporary storage (latch).

In addition, the counters of the digital inputs will be reset.

Definition

void DapiSpecialCommand(ULONG handle, DAPI_SPECIAL_CMD_COUNTER,DAPI_SPECIAL_COUNTER_LATCH_ALL_WITH_RESET, 0, 0);

Parameters

None

Example program

DapiSpecialCommand(handle, DAPI_SPECIAL_CMD_COUNTER,DAPI_SPECIAL_COUNTER_LATCH_ALL_WITH_RESET, 0, 0);


5.3.10. Dapi_Special_DI_FF_Filter_Value_Get

Description

This command returns the filter [ms], in which time interval the digital inputs aresampled.

Definition

ULONG DapiSpecialCommand(handle, DAPI_SPECIAL_CMD_DI,DAPI_SPECIAL_DI_FF_FILTER_VALUE_GET, 0, 0);

Parameters


Return value

Time [ms]

Example program

value = DapiSpecialCommand(handle, DAPI_SPECIAL_CMD_DI,DAPI_SPECIAL_DI_FF_FILTER_VALUE_GET, 0, 0);//Gibt das Zeitintervall zum Abtasten der digitalen Eingangskanäle zurück.


5.3.11. Dapi_Special_DI_FF_Filter_Value_Set

Description

This command sets a filter [ms], in which time interval the digital inputs aresampled.

Definition

void DapiSpecialCommand(handle, DAPI_SPECIAL_CMD_DI,DAPI_SPECIAL_DI_FF_FILTER_VALUE_SET, ULONG time_ms, 0);

Parameters


time_ms=time interval [ms], in which digital inputs are sampled.

Return value

None

Remarks

This command only supports pulse durations between 5ms and 255ms.

If no time is set, the default value (100ms) will be used.

Example program

DapiSpecialCommand(handle, DAPI_SPECIAL_CMD_DI,DAPI_SPECIAL_DI_FF_FILTER_VALUE_SET, 5, 0);// Setzt das Zeitintervall auf 5msDapiSpecialCommand(handle, DAPI_SPECIAL_CMD_DI,DAPI_SPECIAL_DI_FF_FILTER_VALUE_SET, 150, 0);// Setzt das Zeitintervall auf 150ms


5.4. Setting Digital outputs

5.4.1. DapiDOSet1_WithTimer

Description

This function sets a digital output (ch) to a value (data - 0 or 1) for a specified timein msec.

Definition

void DapiDOSet1_WithTimer(ULONG handle, ULONG ch, ULONG data, ULONGtime_ms);

Parameters


ch=Specifies the number of the output, from which it begins to write to (0, 32, 64, ..)

data=Specifies the data values, to write to the outputs

time_ms=Specifies the time, in which an output is set [ms]

Return value

None

Remarks

This function is only supported by our RO-O8-R8 module.

This function will lose its validity, if it is overwritten with other values.

If you want to deactivate this function, you will have to overwrite it with time_ms=0.

Example program

DapiDOSet1_WithTimer(handle, 2, 1, 1000);//Setting channel 2 for 1000msec to 1


5.4.2. DapiDOSet1

Description

This is the command to set a single output.

Definition

void DapiDOSet1(ULONG handle, ULONG ch, ULONG data);

Parameters


ch=Specifies the number of the output to be set to (0 ..)

data=Specifies the data value that is to be written (0 / 1)

Return value

None


5.4.3. DapiDOSet8

Description

This command sets 8 digital outputs simultaneously.

Definition


Parameters


ch=Specifies the number of the output, from which it begins to write to (0, 8, 16, 24,32, ..)


Return value

None

5.4.6. DapiDOSet64

Description

This command is to set 64 digital outputs.

Definition


Parameters


ch=Specifies the number of the output, from which it begins to write to (0, 64, ..)


Return value
