Logging Type; Operating Procedure For Continuous Logging - Mitsubishi Electric FX5 User Manual

Specifying the monitored data
For monitored data, the following devices can be specified. The data types that can be selected include bit/word (unsigned),
word (signed), double word (unsigned), and double word (signed).
Type
*2
Bit device
*3
Word device
Double-word device
*1 Index modification, and indirect specification cannot be specified.
*2 For bit devices, bit specification of word cannot be specified.
*3 For word devices, nibble specification of bit devices cannot be specified.
*4 To specify these devices with the CPU Module Logging Configuration Tool, use T (contact): TS, ST (contact): STS, C (contact): CS, LC
(contact): LCS.
*5 To specify these devices with the CPU Module Logging Configuration Tool, use T (current value): T or TN, ST (current value): ST or
STN, C (current value): C or CN, and LC (current value): LC or LCN.

Logging Type

The following table describes available methods of data collection:
Logging type Data collection method
Continuous logging Continuously collects specified data at specified interval or timing.
Trigger logging Collects specified data at specified interval or timing and extracts a
specified number of data records before and after the satisfaction
of a trigger condition.

Operating procedure for continuous logging

In continuous logging, the CPU module stores specified data in its internal buffer at a specified collection interval or timing
and, at the time of a file save operation, it saves the data in a data logging file residing in the storage memory.
1.
Write the settings into data memory or SD memory card using the CPU Module Logging Configuration Tool.
2.
Instruct the CPU Module Logging Configuration Tool or special relay
registered and continuous logging begins. (The special relay (data logging start) turns on.)
3.
Data collection finishes upon reaching "Number of files to be saved" specified as part of the "Stop" setting configured in
"Operation when the number of files exceeds the set value."
4.
Specify the desired file in the storage memory to read the results of data logging.
*1 This setting is valid only when the data logging setting file is written in the SD memory card. (Page 143 Data logging execution by
special relay)
In continuous logging, data logging files are continuously created, thus allowing the user to read the results of
data logging any time without having to wait for the completion of collection.
To stop continuous logging
The user can completely stop data logging by instructing the CPU Module Logging Configuration Tool or special relay
stop data logging and unregister the data logging settings stored in the CPU module. (The special relay (data logging start)
turns off.)
*1 This setting is valid only when the data logging setting file is written in the SD memory card. (Page 143 Data logging execution by
special relay)
