Description
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 (device/label data) 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
*5*6*7
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 camera 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).
The data accumulating execution time of a camera recorder
*7*8*9
module is stored.
• Accumulating execution time (ms unit): An ms digit is stored
(value to be stored: 0 to 65535).
• Accumulating execution time (s unit): A s digit is stored
(value to be stored: 0 to 999).
The camera event receiving status is stored. (Page 278
Camera event receiving status (Un\G1593 to 1600))
0: Not set
1: Not receiving
2: Waiting for receiving
Details are the same as network camera 1.
The number of times for camera event reception is stored.
When the operating status of the recording function is
'operating' and the camera event receiving status is 'waiting
for receiving,' the number of times for camera event reception
is stored.
(Value to be stored: 0 to 65535)
