To suspend/resume continuous logging
The user can suspend data logging with the data logging settings remaining intact by doing either of the following:
• Instruct the CPU Module Logging Configuration Tool or special relay
logging start) turns off).
• Turn off to on the special relay (Data logging suspend/resume flag).
To resume continuous logging from suspension, do either of the following:
• Instruct the CPU Module Logging Configuration Tool or special relay
logging start) turns on).
• Turn on to off the special relay (Data logging suspend/resume flag).
*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

Operating procedure for trigger logging
In trigger logging, the CPU module stores specified data in its internal buffer at a specified collection interval or timing; it
extracts a specified number of data records before and after the satisfaction of a trigger condition and saves the extracted
data in a data logging file residing in the storage memory. Note that data collection is performed not only at the specified
collection interval or timing but also when a trigger condition is met. In addition, once a trigger condition is met, any
subsequent trigger conditions are ignored.
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 trigger logging begins. (The special relay (data logging start) turns on.)
3.
Wait until the trigger condition is met. (Trigger standby)
4.
The data specified in CPU Module Logging Configuration Tool is collected. (Trigger condition met)
5.
Data collection is completed by collecting as much data as the number of records specified in the CPU Module Logging
Configuration Tool and writing the collected data into the storage memory.
6.
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)
To stop trigger 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.)
