Adding And Changing A Recording Setting - Mitsubishi Electric MELSEC iQ-R Series User Manual

Adding and changing a recording setting

A recording setting can be added and changed while the operation of the recording function is stopped.
The procedures for adding and changing a recording setting differ depending on the CPU module status.
Precautions
• Turn the power OFF and ON or reset a CPU module after adding or changing a recording setting that requires changes in
the CPU parameter and module parameter.
• When changing a program after writing recording settings to a CPU module, the changed device and label are not
automatically specified as sampling targets. To apply changes in the sampling targets, configure the recording settings
again after stopping the recording function, then restart the function after writing the settings to the CPU module.
• If the sampling size of a recording setting exceeds the capacity of the buffer area setting for data sampling of a CPU
module, the recording function cannot start running and a recording setting error (error code: 3026H) occurs in a recorder
module. The sampling size of a recording setting and the required size of buffer area for data sampling can be checked in
the "Recording Setting" screen. In addition, the capacity of the buffer area setting for data sampling of a CPU module can
be checked in the CPU parameter.

• When adding or changing a program after configuring recording settings if the device/label batch specification is enabled,
devices and labels in the added or changed program are also sampled. This may cause the sampling size to increase when
writing the recording settings and the capacity of the buffer size for data sampling may be exceeded.
Without changing parameters
The following shows the procedure for adding and changing a recording setting without changing the buffer area setting for
data sampling and the recording buffer setting.
1.
Switch a CPU module to the STOP/PAUSE state.
2.
Check that 'Stopped' is displayed for all recording settings.
3.
Write a changed program and all recording settings to the CPU module.
4.
Switch the CPU module to RUN.
■Adding or changing a recording setting while a CPU module is in the RUN state
A recording setting can be added or changed by starting/stopping the operation in the "Recording Monitor" screen even while
a CPU module is in the RUN state.
This allows recording settings to be added or changed at the same time according to a changed program when changing and
writing a program during RUN.
1.
If the operating status for a recording setting is not 'stopped,' stop the operation in the "Recording Monitor" screen.

2.
Check that 'Stopped' is displayed for all recording settings.
3.
Write a changed program and all recording settings to a CPU module.
4.
Start the operation in the "Recording Monitor" screen.
*1 When not changing a program, a recording setting can be added or changed individually.
Stop the operation for a recording setting to be changed in the "Recording Monitor" screen, and write the recording setting to the CPU
module.
Before writing the recording setting, check the considerations shown in the following:
Page 44 Considerations for writing items individually
*2 When adding a new recording setting, set the buffer area for data sampling and recording buffer for the setting, then write the CPU
parameters and module parameters.
For the procedure, refer to the following:
