• The device handles the reading and processing of an analog input.
• The read data is a word to 16-bit signed which you can add an offset, enter a scaling factor and activate a low-pass RC filter type software.
• Input resolution specifications are listed in the file adapter hardware.
  Wiring and connections of the equipment described in this manual, must comply the European standard EN60204-1.

	Note: Input resolution specification are reporter in the hardware dossier with the describing the card (or tool).

In the configuration unit, the BUS section must be declared must be declared so that they are present the hardware resources required for the implementation of the ANINP device. Must be present at least one analog input with a maximum resolution of 16 bits.
In the INTDEVICE section of the configuration unit to add the following definition:

;---------------------------------
; Devices declaration
;---------------------------------
INTDEVICE
...
<nome device>  ANINP  Tcamp  IChn  Type

dove:

	Warning: It is necessary that each definition are present on the same line.

;---------------------------------
; Device declaration
;---------------------------------
INTDEVICE
AnSensor    ANINP 2   2.AI01 1

When the system is powered, the device checks the correct input type declaration use the configuration defined in the unit (Type). If the channel diagnostics ends successfully, data is upgraded on the basis of the time of sampling. NIf errors or inaccuracies are found, the st_errcfgState is set to one and the value of the variableoutbitis forced to zero. The conversion of the data output from the device (outbit), in the measure unit required for the application, is activated by means of scale factors (scaleA, scaleB e scaleC) in accordance with the formula:

outUm = (scaleA x outbit / scaleB) + scaleC

In addition to this updated release based on the sample time of the device, is available the outUmF exit, filtered using a charging time tfilter programmable (expressed in ms).

	This feature allows to filter any disturbances and fluctuations superimposed to the wanted signal with the ability to customize the time of Office of the filter charge (tfilter).

A single input can be managed by multiple device ANINP simultaneously, provided that the identification number of the Type entrance, inserted in the device declaration is not less; otherwise the analog input is configured as the last device declared in the configuration file.

The parameter name, condition or command is taken back to the left side of the table.

R
Indicates if its parameter or retentive state (upon initialization of the device maintains state previously defined), or the State that bears upon device initialization.
If the device does not require initialization field ' R ' indicates the value that the parameter or State accept to the card power ON.
R = Retentive
0 = Upon initialization of the device the value is forced to zero.
1 = Upon initialization of the device the value is forced to one.
- = Upon initialization of the device is presented significant value.

D
Indicates the parameter size.
F = Flag
B = Byte
W = Word
L = Long
S = Single Float

Describes all of the conditions that is considered correct or because the command is accepted.
In some cases, limit values are specified for the acceptance of the parameter: If you any values outside the limits set, the data will still be accepted; must be provided appropriate controls of the application to ensure proper operation.
To run a command, all the conditions must be met; otherwise the command is not executed.

A
Access mode.
R = Read.
W = Write.
RW = Read / Write.

ScaleB deve essere impostato diverso da zero, in caso contrario OutUm viene forzato a 0.

The charging time of RC filtertfilter must be set greater than or equal to the time of sampling (Tcamp) device, otherwise, it disables the filter and the OutUmF parameter is updated with the same value as OutUm.

The offset parameter is added to the acquired analog input (outbit), don't execute the check on the overflow sum.

	In the case that a single channel is managed by multiple ANINP with different Type device, the compiler does not detect errors and the channel is set with the last Type declared.

A single hardware resource (each input) can be handled by multiple simultaneously ANINP devices, to the condition that the identification number of the entrance (Type), posted in device declaration (configuration file), is the same; otherwise the analog input is configured as the last device declared in the configuration file.
