Item Description
(20) Occurred Outputs the size (bytes) of the event name for the occurred/restored event.
event name
length
(21) Occurred Outputs the event name for occurred/restored events in Unicode.
event name (When the high speed data logger module is restarted, an event name length of 0 is output.)
(22) Comment Outputs the size (bytes) of the comment at event occurrence/comment at event restoration for the occurred/restored event.
length
(23) Comment Outputs the comment at event occurrence/comment at event restoration for the occurred/restored event in Unicode.
(When the high speed data logger module is restarted, a comment name length of 0 is output.)
(24) Number of Outputs the number of pieces of data that the occurred/restored event is monitoring.
units of data (If "Output data value" is not specified in the settings, 0 is output.)
(25) Data Outputs the total size of (26) data number, (27) data length, (28) data type, and (29) data.

size
(26) Data Outputs the data number for the occurred/restored event.
number By referring to (13) data name, the data name for the data number can be obtained.
However, when compound conditions (number of times or order) are configured with event conditions, any of the following
data is output.
When the number of times is set : 0x1000
When order is set : 0x1001
(27) Data Outputs the data length of data.
length If the data type is bit type, outputs 1 byte.
However, when compound conditions (number of times or order) are configured with event conditions, 2 is output.
(28) Data type Outputs the following values according to the data type specified in the output format.
0: Bit
1: Signed integer
2: Unsigned integer
3: Float
4: BCD
5: String
6: Raw
However, when compound conditions (number of times or order) are configured with event conditions, 2 is output.
(29) Data Outputs monitoring data in binary format according to (27) Data length and (28) Data type.
For details on the output data, refer to (18) in the following section.

However, when compound conditions (number of times or order) are configured with event conditions, any of the following
data is output.
When the number of times is set : number of counts (up to 65535)
When order is set :
1st condition: 1
2nd condition: 2
3rd condition: 3
Normal completion: 0
*1 Data value is rounded to 0.1 millisecond unit when the high speed sampling is specified, and to 100 millisecond unit when the general
sampling is specified.
The size of the event logging binary file is calculated as shown below.
