Data Type FastCH Extraction Conditions
FC
Data from messages with the specified FC (frame control) is acquired in the acquisition memory. When
is set to ON, you can specify FC.
Selectable range: 0x00 to 0x0F
The default setting is 0x00.
Endian
Select the method (endian) to use to store the data in the acquisition memory.
Big: Big endian
Little: Little endian
Start Bit
Set the data extraction start position in terms of the bit position (bit number) from the beginning of the data
nibble. Set it in terms of the number of data nibbles N of Fast CH messages, explained earlier.
Selectable range: 0 to (4× N)
−1
To set the start bit to the most significant bit of each data nibble, specify 4×( n1) where n is the data nibble
number.
Bit Size
Set the number of data bits to extract. Data is extracted from the start bit towards the back of the data. Set it in
terms of the number of data nibbles N of Fast CH messages, explained earlier.
Selectable range: 1 to {(4× N)
−(Start Bit value)}, except FastCH3 is up to 16
If the number of bits of
1:FastCH
is set to 17 or higher, the memory area of 2
:FastCH
will be used. Therefore, to
set the number of bits of
1:FastCH
to 17 or higher, set the 2
:FastCH
input to OFF. To set 2
:FastCH
input to ON,
set the number of bits of 1
:FastCH
to 16 or less.
