10.4.1.1 Examples

• Single Tag update

This example shows how to update one Tag called “Pressure”. There is one hidden form field for the Tag name and its value is "Pressure" which

is the name of the Tag to update.

There is another form field called TagValue, it is a text edit field where the user can enter the new value of the Tag. When the form is shown, the

initial value of the TagValue field is empty.

• Single Tag update with initial value

The only difference between this example and the previous one is the initial value of the TagValue form field. In this case a TagSSI as been

placed in the "value" attribute of the text field. The eWON will replace this placeholder with the current value of the pressure field when the page

is displayed.

• Single Tag update with no-default result page

Again, this is the same example as the first one, here an additional field has be inserted to define which page to show when the FORM update

has been executed correctly. The additional field is hidden, its name is

ResultPageOk and its value is the page to display in case of update success.

• Multiple Tags update

This example shows the syntax for updating more than one Tag at the time. For each TagNameX there must be a corresponding TagValueX. The

first field must have index 1, then the next must follow with an increment of 1.
