Print current values

This function is used to create a simple log of current variable values (process and derived variables) during online operation.

Give a formatting file as the transfer parameter. This function is configured via a dialog mask.

Configurable options are:

System buttons	OK, Cancel, Help
Abort dialog	displays abort dialog during generation in online operation
Select format file	Opens a dialog box for the selection of the *.FRM file. This file is created with the button below. The format FRM is described further below in this chapter.
Start format editor	starts text editor for creation of file
Font	sets font which will be used

Select the file (*.FRM file type by clicking on the "Select format file" button.

Defined keywords are used in the format file. The corresponding variable parameters are entered during online operation instead of the keywords.

Keywords:

@TTA.name	outputs variable names
@TTA.wert	outputs current technical value; ?outputs binary status as value or string variable
@TTA.einheit	outputs defined unit defined for process variable
@TTA.text	outputs text defined for process variable
@TTA.status	outputs current status bit of process variables in succession with short names (from ZENON6.INI)

The following keywords are available for formatting the output page or as general information:

%DATE	outputs current date
%TIME	outputs current time
%PAGE	outputs current page number

Texts for the header and footer can be defined. The sections (header, main section, footer) have to be marked in front and behind the section with "%%". Three empty lines have to be enteres behind the last "%%".

Using tabs will result in problems when outputting texts of different lengths. Only empty spaces can be used for positioning The "@" key character is not counted.

If the deesired format of the actual values is narrower as the space between the TTA key words, a QRF file with the same name can be used. In the QRF file the process variables are assigned to defined markers. Each marker (xxx) begins with a "$" and is defined with a certain syntax.

define $xxx as Variable
- xxx	freely chosen identifier or number
Variable	Variable name

These markers can be accessed in the FRM file The variable parameters are then addressed via other parameters.

$xxx.1	process variable name
$xxx.2	Technical value
$xxx.3	Unit
$xxx.4	Status text

Example of a QRF file's structure:

QRF file "MOMENT.QRF"

define $001 as TTA1
define $002 as TTA2
