1. Even though there are a lot of things to configure creating a new project really is not that complicated If this is your first attempt to create a project it might help to concentrate on one thing at a time to avoid unnecessary confusion caused by switching back and forth between objects and their different property pages A simple workflow is suggested below e First build the desired object hierarchy using the tree view at the left Use the context menus to add cut copy and paste objects and use drag and drop inside the tree view to move existing objects around It is also possible to have a second instance of the configuration software running and copy paste objects between the projects In the property view keep the General property page open and enter names and descriptions for your objects as you create them Do not get lost in detailed object configuration at this time e You should now have an object tree containing at least the hierarchy of menus menu items pages and the basic controls which will be used to display and enter data All objects should be clearly named Now is a good time to go through the menus and configure their basic appearance Select one menu at a time from the LOYTEC electronics GmbH L Vis User Manual 48 LOYTEC tree view and keep the Common Properties page open in the property view For each selected menu enter a menu title in the Text field and select the desired font With the Common Properti

Assign good names to your trend control objects to make it easy to identify the data files and relate them to the trends which are visible on the device Consider to add the name of each trend to the page where the trend is shown so that the user is able to clearly identify each control and its data file If the trend control object name contains non ASCII characters the resulting file name will be encoded in ISO 10646 Unicode and will be transferred to the client in UTF 8 encoding according to the FTP protocol extension RFC2640 Clients who support this extension can then display these file names correctly Most web browser based FTP clients either detect the UTF 8 encoding automatically or provide an option where the user may set the desired encoding To maximize compatibility to existing FTP clients it is desirable to use only ASCII characters for the name of trend control objects An easy way to manually access the files on the device is to use the windows explorer or a web browser and type the following into the address URL field ftp lt user gt lt address gt Replace lt user gt with the user name for data access as defined in the project settings and lt address gt with the IP address or DNS name of the device for example ftp data 192 168 1 20 You will then be asked for the password and the file system contents will be shown You can now navigate to the required files and download them to the local hard disk of your PC

Alarm Generator Properties Once all inputs and the output are connected the alarm generator may be configured on the Alarm Generator property page For each of the connected inputs an independent set of parameters is required The available input points are listed in the top left area of the property page NOTE If logic or arithmetic operations are required to determine an alarm condition for example signal an alarm when TI gt T2 a mathematic object is required to conduct the required operations The result which is conveniently stored into an internal register is then monitored using the alarm generator The suggested workflow to configure the alarm generator is as follows Version 3 1 First select the input point for which the monitoring rules should be configured Define the Alarm Condition using the radio buttons at the bottom left of the page The available choices allow basic monitoring functionality and always define the condition under which the alarm should be SET If the value no longer satisfies the condition the alarm will be cleared To filter out spikes it is usually good to set an amount of time which the alarm condition needs to be satisfied before the alarm is actually set The default of one second 1s often a reasonable value Define the Data Point Value Range Depending on your choice for the condition you may need to enter values either for both minimum value and maximum value or only for one of the tw
