FUNCTIONS
This chapter explains the details on the functions of System Recorder.
1.1

Recording Function

The recording function can be used to output data in a CPU module to a recording file and save it to an SD memory card
inserted in a recorder module when a file saving trigger is satisfied.
The saved recording file can be read in GX Works3 and reproduced on the offline monitor. This can facilitate identification and
analysis of trouble factors and reduce the downtime of a system. (Page 47 Offline Monitor Function)
The following data can be saved as a recording file (recording target data).
Recording target data
Device and label
Event history
GX Works3
1.
Set programs, parameters, and recording settings in GX Works3.
2.
Write them to a CPU module.
3.
Reset the CPU module or turn the power OFF and ON to switch the CPU module to RUN.
The recording function is in preparation, then data sampling and accumulation start according to the recording setting.
Link devices of a network module mounted on the base unit and the buffer memory of an intelligent function module can also
be sampled and accumulated.
4.
Satisfy a file saving trigger.
When the file saving trigger is satisfied, accumulated data and event history files saved in a CPU module are output to a
recording file and saved to an SD memory card inserted in a recorder module.
For the flow to save sampled data, refer to the following:
Page 37 Flow to save sampled data
Up to four recording settings can be set and the recording function can be performed for each setting at the
same time.
Set multiple recording settings and perform the recording function in either of the following cases:
• Setting multiple timings for data sampling and accumulation such as each scan, per day, inter-module
synchronization execution
• Accumulating data even while a file is being saved
sampling and accumulating data in another recording setting.)
