Log files are saved to either RAM or FLASH memory. Log files stored in RAM are lost when the system power cycles. The RAM area is
directory RAM0 with a capacity of 1000KB (1 Megabyte). The FLASH area is directory FLASH0 with a capacity of 256KB. This FLASH0
area is shared with configuration files and program files.
Resource Allocation
To avoid filling a log file and losing data, allocate the system resources. A new log file may be started daily, weekly, or when the existing
data file reaches a specified size. When a log file is filled, have the data log file automatically e-mailed as an attachment or use FTP to
retrieve the file. To have the completed log file automatically e-mailed, enter a recipient’s e-mail address ([email protected]) and
optional subject and message.
Discarding the Oldest Files
To automatically discard the oldest data logs when system resources are exhausted, check the discard oldest radio button. This discards
the oldest file with the name shown in the File Name box. This rule applies independently for each log file rule set.
The specific rules for resource management are as follows:
If a file is full (i.e. its size setting is met), disregard the schedule, e-mail the file to the listed recipients, and request a new file. Until the file
fills, check the schedule. If the log file should be e-mailed now because of daily schedule settings, e-mail the file and request a new file.
The e-mail command only applies if e-mail is configured, but the new file request always applies.
When a new file is requested, check the discard oldest or stop logging setting. If discard oldest is selected, add up all log file sizes. If this
much free space is not available, delete the oldest file with a name prefix matching the log configuration requesting a new file. If there is
only one (or fewer) older file, revert to stop logging rules. If stop logging is selected (by configuration or by default), verify there is room
for 50% of this file. If so, create the file. If not, disable this log.
Data Points
Use the Data Points page to select which local registers are logged by each of the available data loggers.
All the available local registers are listed on this page. Select the appropriate checkbox to include this data in one of the three log files.
