This document describes the procedures for setting the MELSEC iQ-R series camera recorder module RD81RC96-CA and
network camera, as well as each function of GX Works3 to perform these three steps.
In addition, an example is provided to describle how to identify the cause of the error by monitoring data recorded by the
recording module and using the video from the network camera, analysis function of GX Works3, and GX LogViewer.

Description
In addition to all the devices of the programmable controller CPU, labels and
videos recorded by cameras are sampled and recorded with timestamps.
The recording function outputs the data of the CPU module and the video data
recorded by a network camera to a recording file when a file saving trigger is
satisfied, and saves the file to the destination specified in the recording setting.
Various recorded data can be replayed in synchronization to easily identify the
timing at which an error occurs.
The offline monitor function can be used to replay the recording files saved in the
SD memory card or file server of the camera recorder module on the offline
monitor. The GOT monitor display can also be replayed by starting the GOT
offline monitor.
The time required to determine the root cause of the error can be reduced by
tracing the sequence program.
The data flow analysis function searches for the event history of devices, labels,
parameters, and current value changes in the program that cause the selected
device or label to change, and displays the related items in a flowchart.
