PCL-818L Analog Input block (not recommended)

Block Output Data Type
If you select 16 channels (Input coupling parameter
Single-ended), enter numbers between 1 and
16. If you select
coupling parameter set to
enter numbers between 1 and 8. For example, to use the first and second
analog output (A/D) channels, enter
Number the channels beginning with 1 even if this board manufacturer starts to number the channels with 0.
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)
-5 to +5
-2.5 to +2.5
-1.25 to +1.25
-0.625 to +0.625
For example, if the first channel is -2.5 to +2.5 volts and the second channel is -5 to +5 volts, enter
The range settings must correspond to the DIP switch settings on the board.
If you need a -10 to +10 volt range, perform the following workaround. Note that the PCL-818L Analog Input block sets bits G1 and G0 in the board register, but cannot set or read the board jumper.
On the board, move the JP7 jumper to the 10 volt range (see the manufacturer documentation for details).
In the Range vector parameter,
Setting the JP7 jumper to the 10 volt range doubles all input voltage ranges.
Use a Gain block to multiply the value by 2. This matches the output voltage to the input voltage for all ranges.
From the list, select one from the following list of input modes:
Single-ended channels (16 channels)
differential channels (8 channels)
Your choice must correspond to the MUX switch setting on the board.
Enter the base sample time or a multiple of the base sample
-1 means sample time is inherited).
Enter the base address of the board. This entry must correspond
to the DIP switch setting on the board. For example, if the DIP switch
setting is 300 (hexadecimal), enter
