Project Data Saving Function - Mitsubishi Electric MELSEC iQ-R Series User Manual

Project data saving function

This function can be used to save project data used when playing a recording file to a save destination where the recording
file is saved.
It is available when using an RnCPU or RnENCPU as a CPU module.
When configuring multiple modules, project data is saved in a module set as the main one.
Page 67 Operation of the recording function when configuring multiple modules
Precautions
If multiple peripheral devices communicate with a CPU module while project data is being saved in a recorder module/camera
recorder module, a communication response to each peripheral device may decrease.
In consideration of the performance of the communication response, configure the setting according to the system, such as
changing the setting in the parameter setting of the peripheral device so that the timeout time becomes longer.
When using multiple recording settings, the processing time for saving project data and the time during which a
communication response decreases can be reduced by saving a recording file for each setting to the same save destination.
Methods for saving project data
The following table shows the methods for saving project data.
Method
Performing automatic saving in the
module parameter
Turning the buffer memory ON
*1 For details on the operating status of recording, refer to the following:
Page 63 Operating status
■Performing automatic saving in the module parameter
When specifying automatic saving in the module parameter of a recorder module/camera recorder module, project data is
automatically saved to a save destination for a recording file specified in the recording setting for which the operation starts
after starting recording.
By saving project data when recording starts, only project data during recording operation is saved.
Automatic saving is enabled by setting "Automatic Saving at Recording Start" to "Save" in the module parameter, writing the
setting to a CPU module, and turning the power OFF and ON or resetting the CPU module.
For details on the module parameter, refer to the following:
Page 99 Project data saving setting
Once enabled, even when changing a save destination for a recording file in the recording setting, the setting when recording
starts is automatically applied to the save destination for project data.
*1 For changing the recording setting after stopping recording while project data is being saved, refer to the following:
Page 88 When stopping recording during project data saving
When configuring multiple modules, set this method in the module parameter of a module set as the main
one.
Timing
Recording starts.
The buffer memory of a recorder
module/camera recorder module
turns ON.
Purpose
Use this method to automatically save project data when recording starts.
Use this method to save project data at any timing.
It is available only during recording operation.
