Comparison Condition (Condition)
The data trigger condition is met when the result of comparing the data pattern or reference value to the
input signal’s data field meets the specified comparison condition.
True
When the value matches the data pattern
False
When the value does not match the data pattern
Data=a
1
When the value is equal to the reference value
Data≠a
1
When the value is not equal to the reference value
a≤Data
1
When the value is greater than or equal to the reference value
Data≤b
1
When the value is less than or equal to the reference value
a≤Data≤b
2
When the value is within the reference range (including the reference values)
Data<a, b<Data
2
When the value is outside the reference range (excluding the reference values)
1 Set one reference value
2 Set two reference values
Data Pattern (Hex/Bin)
If the comparison condition is set to True or False, set the data pattern for the data whose length was set
with DLC in hexadecimal (Hex) or binary (Bin) notation.
Reference Values (a and b)
If the comparison condition is set to Data = A, Data ≠ a, a ≤ Data, Data ≤ b, a ≤ Data ≤ b, or “Data < a or
b < Data,” set the reference values in decimal notation. You must set the byte order (Endian), sign (Sign),
and comparison range (MSB or LSB). The selectable ranges are as follows:
Unsigned
(Unsign)
0 to 9E+18
The selectable maximum value is limited by the data length and bit position, which are
determined by the DLC and MSB/LSB settings, respectively.
Signed
(Sign)
−9E+18 to 9E+18
The selectable minimum and maximum values are limited by the data length and bit
position, which are determined by the DLC and MSB/LSB settings, respectively.
The value is displayed in scientific notation when the number of digits exceed seven
(example: 1 10).
If the comparison condition is a ≤ Data ≤ b or “Data < a or b < Data,” the two reference values are
automatically adjusted so that the lower limit is less than or equal to the upper limit.
Byte Order (Endian)
Set the byte order of the data stream to Big Endian (Big) or Little Endian (Little). The following figure
illustrates a 4-byte data stream on the bus. The data field value is 12345678 in hexadecimal notation.

Sign (Sign)
Set whether to use a signed (Sign) or unsigned (Unsign) data format.
The selectable range of data reference values varies depending on whether the data is signed or unsigned.
