CPU Parameters

This section shows the CPU parameters required to be set for using a CPU module for System Recorder.

Memory/device setting

The following shows the screen for setting each item in the buffer area setting for data sampling of a CPU module.
Buffer area setting for data sampling
Item Description
Device/Label Data Select "Use" or "Not to Use."
Sampling
Total Capacity The total capacity of an area used by a system to temporarily store device/label data is displayed.
*1
Setting No.1 to 4 Set the capacity of an area used by a system to temporarily store device/label data.
*1 Can be set only when selecting "Use" for "Device/Label Data Sampling."
*2 The maximum value and default of the capacity differ depending on the module type.
R04CPU, R04ENCPU, R08CPU, R08ENCPU, R08SFCPU, R16CPU, R16ENCPU, R16SFCPU: 4 M Byte
R32CPU, R32ENCPU, R32SFCPU, R120CPU, R120ENCPU, R120SFCPU: 6 M Byte
Precautions
The buffer area for data sampling is a temporary area for sampling data. Set the total number of device and label points to be
sampled to a value equal to or smaller than the capacity of the buffer area setting for data sampling. Otherwise, an error
occurs when recording starts and the recording function does not run.
