//Create an Array to store each line of the log file:
var logFile = new Array();
//create a string with the name of the log file (the same that
was configured in DM1 Settings)
var logFileName = “j1939_DM1_log_file.csv”;
//now a variable with the default log path:
var path = “/opt/logfiles/”;
//now read the file
logFile = readFile(path + logFileName);
//after reading, the data has to be assigned to the table
//(change tableID to the tableID your table has):
var tableID = 332;
setProperty(tableID, “Table Data”, logFile);
Here is a screenshot from the device displaying the log file contents:
Note: You can scroll through the table if “Set As Input” property of the table is enabled.
Note 2: The JavaScript readFile function is currently limited to only read the first 2MB of a file.
If the log file is larger than that, the rest of the content is not shown. Consider deleting the log
file if the size of it gets too big.
