Description
The path to the setting type folder for a recording file last saved to an SD
memory card is stored.
It is initialized to '0' when the operating status switches to 'operating' after a
file saving trigger is satisfied or starting the recording function.
(Example) When the path to a recording file is /SD/RECORD/RC1/
1TS01_001, /SD/RECORD/RC1/ is stored.
The path under the setting type folder to a last saved recording file is stored.
It is initialized to '0' when the operating status switches to 'operating' after a
file saving trigger is satisfied or starting the recording function.
(Example) When the path to a recording file is /SD/RECORD/RC1/
1TS01_001, 1TS01_001 is stored.
When the operating status of the recording function is 'operating,' the
number of times that a recording startup trigger was detected to have been
satisfied is stored.
(Value to be stored: 0 to 65535)
When the operating status of the recording function is 'operating,' the
number of invalid recording startup triggers among the recording startup
triggers detected to have been satisfied is stored.
(Value to be stored: 0 to 65535)
When the operating status of the recording function is 'operating,' the
number of times that a file saving trigger was detected to have been satisfied
is stored.
(Value to be stored: 0 to 65535)
When the operating status of the recording function is 'operating,' the
number of invalid file saving triggers among the file saving triggers detected
to have been satisfied is stored.
(Value to be stored: 0 to 65535)
The average value of device and label sampling intervals is stored (unit:
millisecond).
It is calculated based on eight moving averages.
If an average value exceeds 4294967295 milliseconds, 4294967295 is
stored.
The average size of devices and labels to be sampled at a time is stored
(unit: KB).
The maximum period during which a device and label can be sampled in the
current setting is stored (unit: second).
A period is calculated with the following formula each time a device and label
are sampled.
• Recording buffer size  Average device/label sampling size  Average
device/label sampling interval
If a period exceeds 4294967295 seconds, 4294967295 is stored.
Whether the recording buffer capacity is sufficient for a saving period set in
the recording setting is stored.
0: Sufficient
1: Insufficient
'1' (insufficient) is stored when a value in 'Device/label maximum sampling
period' (Un\G1583 to 1584) is smaller than a set saving period.
If a value in 'Device/label maximum sampling period' (Un\G1583 to 1584)
and a set saving period are extremely close, '0' (sufficient) and '1'
(insufficient) may be stored alternately in a short time.
It is initialized to '0' (sufficient) when the operating status switches to
'operating' after starting the recording function.
The data sampling execution time of a CPU module is stored.
When using a recording startup trigger or specifying a device as a file saving
trigger, the time required for trigger detection is also included.
Note that when an interrupt program is executed during the END processing,
the execution time of the interrupt program is also included in the sampling
time, and if the program execution time of a CPU module is shorter than the
accumulating execution time of a recorder module, the accumulating
execution time is included in the sampling execution time of the CPU
module.
• Sampling execution time (ms unit): An ms digit is stored (value to be
stored: 0 to 65535).
• Sampling execution time (s unit): A s digit is stored (value to be stored:
0 to 999).
