Byte Count
Set the method for extracting the data area of the collected data frames.
Auto: All data is extracted. Normally use this option.
1 to 8: The specified number of bytes of data are extracted. Data is extracted starting from the start of the data.
Byte Count is enabled when big endian byte order is in use. When little endian byte order is in use, Byte
Count is always set to Auto.
Start Bit
Specify the bit number of the data extraction starting point.
0 to 63
Bit Count
Set the number of data bits to extract. The range that you can specify varies depending on the data type.
Unsigned, Signed: 2 to 32
Float: the bit length that can be set is only 32
Logic: 1 to 8
Byte Order
Select the method (endian) to use to store the data in the acquisition memory.

You can monitor up to 60 sub channels with a single port. If the input is turned on for all the sub channels
and the bit length of each sub channel is 16 bits or less, you can monitor all 60 sub channels. However, the
amount of memory is limited, so each time that the length of a sub channel is set longer than 16 bits, the
DL850EV turns the input of sub channels off (sets them so that they cannot be monitored) in decreasing
order starting with sub channel number 60 until the memory usage is within the memory limitations.
