General Reference Guide eWON Configuration Figure 60: Storage Memory config page (8MB) Figure 61: Storage Memory config page (32MB) Flash Memory zone Size Description Historical data 1 to 3 MB Retentive values 64 KB System Config 256 KB Communication Config 64 KB /usr partition 1 to 16 MB /sys partition 0 to 1 MB Used for storing historical data. This file system is located in its own partition. This partition contains 3 files that contain circular data: • Incremental recordings • Events logging • Alarm history logging Each of those files receives a predefined maximum amount of space. When this amount of space is reached, then the older data are erased, in order to free space for the new data. This is a fixed flash memory block that contains the retentive values. The dimension of that block does not need to be modified. The System configuration is: • All eWON parameters (except COM) • All Tags definitions • All Users definitions The communication configuration needs to be saved in a distinct block in order to allow formatting any other data in the eWON without risking to loose contact with the device (Ethernet IP address, PPP configuration etc.). This configuration uses a fixed memory size and is stored with a special mechanism that prevents loosing the configuration even if power is lost at any time during the configuration update. The only risk is to loose the last modification made after last save occurred. Communication Configuration consists in all the configuration information that appears in the ComCfg.txt file. This partition uses a different file system, allowing to create a larger number of files and to use a larger total flash memory. This file system is also very robust in case of power lost during the time when operations are performed on the files. This partition can be used through the eWON’s FTP server or using the eWON’s BASIC scripts. If the /sys partition does not exists, the program and the configuration are then stored in this partition (see below: /sys partition). This partition uses the same file system as the /usr partition described above. Its function is to store the program and the configuration. The configuration includes all the information that appear in the config.txt file. When this partition is formatted, the configuration and the program are erased, but the current configuration and program are still in memory. If the eWON is rebooted at that moment, it will use after restarting a default configuration and an empty program. When the configuration or the program are saved, the eWON uses this partition to save a config.sys and a program.sys files. These files are used internally by the eWON and should not be modified by the user. If the partition size is set to 0 MB (eWON with only 8MB), then the partition is not created, and all /sys data are saved in the "/usr" partition.

3.3.4.5.2 Erase & Format Figure 62: Erase & Format panel This control panel function is to allow you to erase some parts of the eWON storage area. General Reference Guide eWON Configuration Control Description Format All partitions Format All partitions Validating this checkbox will result in formatting /usr and /sys partitions. Format /sys partition Validating this checkbox will result in formatting /sys partition. Format /usr partition Erase config Validating this checkbox will result in: Formatting only /usr if /sys is not stored in it Formatting /usr AND /sys if you have chosen a storage configuration with /sys set to "0" Erase config files Validating this checkbox will result in erasing the eWON configuration, except for its communication information (comcfg.txt). Clicking on Execute after having selected this checkbox will disconnect you from your current eWON session. Erase program Validating the checkbox will result in erasing the eWON Basic script file program.bas. Format Historical Recording File System Erase "Historical Recording" file Erase "Events" file Erase "Alarms History" file Format Historical Recording File System Validating this checkbox will result in erasing the 3 files that stores the eWON’s internal history, which means all of the three following controls together in this table. Validating the checkbox will result in erasing the binary format ircall.bin file that contains the binary values of all the Tags that are defined in the eWON. Validating the checkbox will result in erasing the text format events.txt file that contains the history of all of the (maximum) 762 last events that have been logged in eWON. Validating the checkbox will result in erasing the text format hst_alm.txt file that contains the history of the alarms for the Tags that have been defined in the eWON.
