Operation Of The Recording Function - Mitsubishi Electric MELSEC iQ-R Series User Manual

Operation of the recording function

The following shows the operations of the recording function.
Start
To start the recording function, perform either of the following operations:
• Switch a CPU module from STOP to RUN.
• Start the recording function in the "Recording Monitor" screen.
*1 The operating statuses for all written recording settings switch to 'preparing,' then 'operating' after the preparation is completed.
*2 The operating status for a target recording setting switches to 'preparing,' then 'operating' after the preparation is completed.
Devices and labels are sampled in a CPU module while the recording function is running even if they are not
accumulated in a recorder module/camera recorder module. Therefore, the END processing time is extended
in a scan of a sampling timing.
Effect of the recording function on the END processing time can be checked in the "Recording Status Detailed
Information" screen of the recording monitor. (Page 145 Recording Status Detailed Information Screen)
■Data when configuring the recording setting and data written to a CPU module
To use the recording function, the following information must match
If they do not match, a recording setting error (3027H or 3028H) occurs and the recording function does not start. In this case,
the recording setting must be written to a CPU module again.
• Project information (parameter and program including device and label settings) when configuring the recording setting
• Parameter and program written to a CPU module
However, when using a module with any of the following firmware versions, a recording setting error does not occur and the
recording function starts for the next time (restart) even if the information above does not match due to program change while
the recording function is running.
• RnCPU or RnENCPU: '55' or later
• RnSFCPU: '24' or later
• Recorder module: '04' or later
• Camera recorder module: '01' or later
For details on changing programs while the recording function is running, refer to the following:
Page 76 Program change while the recording function is running
*1 Even when not editing programs, they may be different from those that were applied when configuring the recording setting after
converting the programs. Make sure to write the recording setting and programs to the CPU module.
Precautions
• The recording function starts running after preparation; therefore, it takes time to be ready for data sampling, reception, and
accumulation.
• For devices and labels, a timing when sampling and accumulation start differs for each recording method.
When selecting "File Saving Trigger Only" for the recording method: Sampling and accumulation start when the operating
status switches to 'operating.'
When selecting "Recording Startup Trigger + File Saving Trigger" for the recording method: Sampling starts when the
operating status switches to 'operating' and accumulation starts when a recording startup trigger is satisfied.
• For video data, regardless of the recording method, reception and accumulation start when the operating status switches to
'operating,' the communication with a network camera is established, and video data is delivered from the network camera.
