Library

xPC Target Library for Advantech

Scaling of Input to Output

Hardware Input	Block Output Data Type	Scaling
Volts	Double	1

Block Parameters

Channel vector

Enter numbers between 1 and 16. For example, to use the first and second analog input (A/D) channels, enter

[1,2]

Number the channels beginning with 1 even if the board manufacturer starts numbering the channels with 0.

Range vector

Enter a range code for each of the channels in the channel vector. The range vector must be the same length as the channel vector. This board allows the range of each channel to be different.

The following table is a list of the ranges for this driver and the corresponding range codes.

Input Range (V)	Range Code
-10 to +10	-10
-5 to +5	-5
-2.5 to +2.5	-2.5
-1.25 to +1.25	-1.25
-0.625 to +0.625	-0.625
0 to +10	10
0 to +5	5
0 to +2.5	2.5
0 to +1.25	1.25

For example, if the first channel is -10 to +10 volts and the second channel is 0 to +5 volts, enter

[-10,5]

The range settings must correspond to the DIP switch settings on the board.

Sample time

Base sample time or a multiple of the base sample time.

Base address

Enter the base address of the board. This entry must correspond to the DIP switch settings on the board. For example, if the base address is 300 (hexadecimal), enter

0x300
