  1. Hi Piet, Suggestions for features are most welcome, but there is no guarantee for implementing them. Please explain what you need and why so we and the forum users can offer alternative or join to your request. Can you explain?
  2. Hi hotwires, This is just the way TCP works. A connection can remain established for days or even weeks without a single packet being exchanged. The disconnection should be detected as soon as the connected side tries to send data. A disconnected device can't send any data, so there's no way to know that it's disconnected until it fails to respond to a query. In general, the only way to detect a disconnected device is to try to send data to it. If you don't ever send any data, you're simply not assured of detecting it. Notes: When the server regains connectivity (back on the net) it will automatically update the number of connections value.

    Alarm summary on Web Server?

    Hi _MELLON_, You can build a widget that use the "Alarm Status Struct". For example, if I have 3 Alarms in my application I can use "Alarm Status Struct -> Alarm State[0]" "Alarm Status Struct -> Alarm State[1]" "Alarm Status Struct -> Alarm State[2]" to trigger alert (text or some graphic element). Any Alert can be saved in a Data Table and be acceded later on.

  10. Hi Kestralcontrols, In order to download a file that stored on the SD card via a web server "Hyper Link" use the prefix "ExternalSd" before the path to the file. For example, lets assume the next file exist on my SD card "/MyDir/MyFile.txt". and that I have a "Hyper Link" widget that it "Tag:Link" is tag PATH_TO_FILE. If I will set PATH_TO_FILE to "/ExternalSd/MyDir/MyFile.txt" and press on the "Hyper Link" on the web site the file will be downloaded:

    How to use "Read from DTI row, Write to SQL"?

    Hi Priyanka Shahi, Let's go over the steps to use: #1. Create a "UniLogic Query" for parameter A When you are using "Read from DTI row, Write to SQL" function block the first parameter is Query that belongs to an SQL data base. for example: In this example I've created a Query named "My Query" that belongs to data base "Database1". When I will use "SQL Query" function block with "My Query", UniStream will connect to "Database1" according to the specifics I gave it - IP = 1.2.3.4, Port = 1234, etc... The SQL query syntax will be added in the next steps. #2. Add a Data Table for parameter B Let's add the next Data Table: 12 rows of the next struct {"ID" - UINT8, "Age" - UINT8} #3. Add SQL syntax our "UniLogic Query" The SQL syntax of the "UniLogic Query" will be the code that will be preformed in the SQL Server. One can use the "Add New Query" (see image below) button, when he creates a "UniLogic Query", in order to create in a fast & convenient way the SQL syntax for the SQL operation he wants: For example , let's say we do not have a SQL table that feet to our table created above in our SQL Server. If we use "Add New Query" -> "Script from Data Table as" -> "CREATE", and link the the table we created, we will get: /************************************************************************************* Use this query in a 'SQL Query' Ladder Element. The PLC will create an SQL Table with a strcture that matches the DTI's structure. ****************************************************************************************/ IF NOT EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[Table1]') AND type in (N'U')) BEGIN CREATE TABLE [Table1]( [ID] [int] NOT NULL, [Age] [int] NOT NULL ) END This is the exact code we need to create the Data Table we created in our SQL Server. The table already exist and you want to add the data? no problem, let's use the "Add New Query" -> "Script from Data Table as" -> "INSERT": UniLogic does the job for us. #4. Add 'From Index' for parameter C and 'Number of rows to write' for parameter D Straightforward. Just add the values that detriment from what index you start and what are the number of rows you want. If for example we use: 'From Index' = 2 'Number of rows to write' = 2 If the query syntax is the "INSERT" query before, 2 rows of the Data Table from index 2 will be added to the table in the SQL Server.
