Http Server Functions/ Web Pages
In this example DT200 (variable name "Counter") is read from the PLC and interpreted as
number 'n'. In a loop that follows, 'n' dashes ('-') are output. The resulting HTML page looks as
follows:
The character { in Java Script must be followed by a space character, tab
character or a new line. Otherwise it is interpreted as a PLC data field.
Example:
for (i=0; i<n ; i++ ) {document.write('-'); }
will generate a compiler error. But the following code will work as expected:
for (i=0; i<n ; i++ ) {
document.write('-');
}
