11 DATA LOGGING FUNCTION
11 DATA LOGGING FUNCTION
This function collects data at a specified interval or a desired timing and stores them as a file on the SD memory card or
function memory
*1
.
The entire data logging function allows the entry of up to 10 data logging settings.
*1 For the CPU modules that can use the function memory, refer to the availability of storage location. ( Page 183 Availability)
*2 For details on the data to be collected, refer to the following. ( Page 171 Data to Be Collected)
*3 For details on continuous logging and trigger logging, refer to the following. ( Page 178 Logging Type)
• Without an SD memory card, the data logging can be performed by using the function memory and the file
transfer together to save the data. ( Page 187 When the data storage destination memory is the
function memory)
• For system configuration, specifications, the procedure for operating and configuring this function in the
CPU Module Logging Configuration Tool, which are not covered here, refer to CPU Module Logging
Configuration Tool. ( Page 945 How to Use CPU Module Logging Configuration Tool)
• This function cannot be used in the R00CPU.
• When using the Process CPU (redundant mode), refer to the following as well.
