• Data
The instrument triggers by detecting a data value. Specify the size, position, and condition.
Comparison Size (Size)
Set the data length to be compared. The data pattern with the specified data length is compared to
the input signal data pattern. If “0” is specified, the instrument assumes that a point has been detected
regardless of the input signal’s data value.
Selectable range: 0 to 8 bytes
Comparison Start Position (Position)
Set the data pattern start point. The left end of the data is position 0.
Selectable range: 0 to 254 bytes
• If the comparison size (Size) is set to 0, comparison start position (Position) cannot be set.
• The selectable range for position is limited so that Size + Position is less than or equal to 255.
Comparison Condition (Condition)
The data trigger condition is met when the relationship between the data pattern or the reference value and
the input signal data value matches 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
If the comparison condition is set to True or False, set the data pattern for the specified size 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 Size 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 Size and MSB/LSB settings, respectively.
The value is displayed in scientific notation when the number of digits exceed seven (example:
110).
