Thresholds
Thresholds are set to trigger actions based on events. The event occurs when a source register value meets criteria defined by a thresh-
old rule. The result of the event can include setting another register to a specific value, sending an e-mail or text message notification, or
logging an event or data to a log file.
Threshold rules are created using the System > Action Rules > Thresholds > Thresholds - Expanded View page. In the example shown,
a threshold rule has been set up to track when Node 1’s I/O point 1 (Modbus register 17) is on. Node 1’s I/O point 1 is a discrete input
wired to an on/off switch. Once saved, this threshold rule can be chosen as an event to log in the data log and event log pages (Ad-
vanced > Data Logger).
After making changes to any screen, click the Update button to submit these changes to the device. Also go to the System > Setup >
Config File page and click the Save or Save As buttons to save the configuration changes.
If you leave a page after making changes and have not submitted those changes to the device, the changes are lost.
Data and Event Logging
Event and data logging is defined using the Advanced > Data Logger pages.
Once the Data Logger tab is selected, there are four pages used to set up data and event logging:
Log Files. Sets up the event log and data log files. One event log and three data log files are available for logging. Use the Prev and
Next buttons to move between the Event Log, Data Log 1, Data Log 2, and Data Log 3 set-up screens.
Data Points. Displays a list of the device registers. Select which registers to log to Data Log 1, Data Log 2, or Data Log 3.
Events Logged. Displays the list of events established in the System > Action Rules > Thresholds page. The events may be logged
when True or False.
File List. Displays the list of log files created.
Log Files
To set up a data log file, follow these steps:
1. From the Log Files page, select the file location (RAM0 or FLASH0) and enter a file name. The file name must be eight characters
or less and the extension must be .txt. An example file name is DataLog1.txt. Files saved in RAM0 will be lost when the power
cycles to the device. Files saved in FLASH0 are saved until they are deleted. The name entered in the File Name field is a prefix.
The system appends this file name with a date and time stamp. When the first log file is filled, a second log file using the same
prefix and a new date and time stamp is created.
2. Select the Enable Logging checkbox.
