*1 A value is not updated when the operating status is 'stopped.'
*2 Available only for a camera recorder module with "Main" selected for the recording operation setting.
*3 '0' is stored when powering ON or resetting a CPU module.
It starts from '0' when the operating status switches to 'operating' after adding or changing a recording setting and starting the recording
function. When it reaches 65535 times, it returns to 1 and continues counting.
*4 If the number of times for data sampling is not sufficient for calculation after data sampling starts, an error occurs.
It is cleared to the initial value (0) when the operating status switches to 'operating' after starting the recording function.
*5 A value is updated when data in a CPU module is sampled.
*6 When the sampling execution time is 23.6 ms, it is stored as follows:
Sampling execution time (ms unit): 23
Sampling execution time (s unit): 600
*7 Initialized to '0' in any of the following cases:
The power is turned ON.
A CPU module is reset.
The recording function is started.
*8 A value is updated when data accumulation for a camera recorder module is completed.
*9 When the accumulating execution time is 23.6 ms, it is stored as follows:
Accumulating execution time (ms unit): 23
Accumulating execution time (s unit): 600
*10 A value is not stored before the number of average bit rates required for calculation is sampled after data accumulation starts.
It is cleared to the initial value (0) when the operating status switches to 'operating' after starting the recording function.
For details on 'Average bit rate' (Un\G34473 to 34474), refer to the following:

■In recording operation (Un\G1501)
Each value is stored at each timing as follows:
Value
0 (stopped)
1 (operating)
*1 When the operating status is 'saving trigger establishment' or 'saving,' a value is stored at either of the following timings:
Main module: After saving is completed in the main module and all sub modules with recording target data
Sub module: After saving is completed
*2 If there is any sub module that cannot start operating, a value is stored when the other sub modules and main module start operating.
■Recording start error (Un\G1502)
Each value is stored at each timing as follows:
Value
0 (no error)
*1
1 (error exists)
*1 An error cause can be checked in 'Recording start error cause' (Un\G1503).
7 CAMERA RECORDER MODULE (DETAILED SPECIFICATIONS)
276
7.4 Buffer Memory
Main module
• The recording function is stopped, and the main module and
all sub modules with recording target data stop operating.
• A module stop error occurs in the main module.
• The main module and all sub modules with recording target
data start operating after starting the recording function.
Main module
• The operating status of the main module switches to
'preparing' after starting the recording function. (It is initialized
to '0' (no error).)
• A CPU module or the main module cannot start recording
due to an error after starting the recording function.
• There is any sub module with recording target data that
cannot start recording after starting the recording function.
Sub module
• The recording function is stopped, and the camera recorder
*1
module itself stops operating.
• A module stop error occurs in the camera recorder module
itself.
• A module stop error occurs in the main module.
• The camera recorder module itself starts operating after
*2
starting the recording function.
Sub module
• The operating status of the camera recorder module itself
switches to 'preparing' after starting the recording function. (It
is initialized to '0' (no error).)
• The camera recorder module itself cannot start recording due
to an error after starting the recording function.
