- If “#PASSWD:xx” is suffixed to the pointID from which the link is called (whether this be an actual display
point or just “LINK”), a popup is shown before the link is followed. The password can be a value between 1
and 65535, but is a fixed value, and can only be changed in the graphics editor, before conversion. Entering
a wrong password will keep the “Enter Password” dialog box open with a message: “Incorrect Password!”,
upon which the user can try again. To close the dialog box, press the “C” button.
-
Writing “#MODBUS:xx” after the page
name in the link field allows following
that link by setting Modbus register
3044 or 3046 from the Modbus master.
xx is the value used for the
corresponding link, each link should
have a separate value.
For example, the link field can contain
“alarm.htm#MODBUS:13”, which
means that the alarm.htm page will be
opened if “13” is written to “open page
register” 3044 or 3046.
This feature is used to “force” pages to appear. The links will most likely be hidden from the user, by putting
them in a small “invisible” box in a corner of the screen (10px X 10px in the background colour) or by putting
them on a (password protected) “settings page” in your project, and are thus only activated from the Modbus
master side when user action is required. The pages can be “force shown” at any given time, meaning the
user doesn’t have to be on the page containing the link for the linked page to “pop up” when instructed so by
the Modbus master. This function is only available during slave mode operation.
-
If “#HISTORY” is suffixed to the pointID from which the link is called (in
this case, the linked must be called from one of the 250 points), the
history graph window is opened when the link is clicked, and the latest
values (history, trend) is requested from the Modbus master. The
history functionality is explained later in this document .
This function is only available during slave mode operation.
- If “#LUT” is suffixed to the pointID from which the link is called (in this
case, the linked must be called from one of the 250 points), a graphical
conversion table (look-up table) is opened and data is requested from
the Modbus master device. The Modbus master has to send the
conversion table data for the requested point. The look-up table
functionality is explained later in this document .
This function is only available during slave mode operation.
Strings / texts
It is possible to define a text object that loads a string from certain registers by selecting the “Show Point Value”
selection box and entering “STRING” as a text. String selection is done by changing the object value. The
object’s value can be preselected using format “STRING_XXYY” where XX is the string section number and YY
is the selected string. See the section “ String Variables ” later in this document for more details.
