This document describes the procedures for setting the MELSEC iQ-R series recorder module RD81RC96 and network
camera and functions of GX Works3 for implementing these three steps.
In addition, procedure examples for determining the trouble cause by monitoring the data recorded by the recording module
and using the video of the network camera, analysis function of GX Works3, and GX LogViewer are described.
Description
In addition to all the devices of the programmable controller CPU, labels and
camera videos are sampled and recorded with timestamps.
The recording function outputs the data of the CPU module to a recording file when
a file saving trigger is established and saves it in the SD memory card of the
recorder module. The camera recording function uses a network camera
connected to the built-in Ethernet of the CPU module to record the video of the
camera synchronized with the CPU module.
The timing of the error occurrence can be easily determined by synchronizing and
replaying the various recorded data.
The offline monitor function replays the recording files saved in the SD memory
card of the recorder module on the offline monitor. In addition, starting the GOT
offline monitor replays the monitor screen of the GOT.
The time taken to determine the root cause of the error can be reduced by tracing
the sequence program.
The data flow analysis function searches for event histories 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.
