WinTr Scada Software

There is two main way to access WinTr Scada Tags remotely. Opc Server and SQL Server. This access can be from the local computer or remote computer or over an internet. With WinTr's Opc Client and SQL Server Services other WinTr stations or the softwares which can use these services can communicate. Here we will try the explain ohw to reach WinTr variables via Internet Explorer browser.

In many automation application administrators want to watch process datas remotely. This can be made by creating many scada stations.Of course buying many scada software would be very expensive. Best way is moving process datas to the Intranet or Internet environment. Thus whitout paying extra price all users can access to data via browsers in order to watch or modify datas.

WinTr doesn't have to located at the hosting server. It can be locate any computer that server can reach.WinTr reads all the Tags from the first line of the database table which are selected as Sql Inp/out and updates them If their values change. You need to do is design a web page which can perform a read and write operation at the first line of the that Tag's column. You can reach historical datas with the same way as well. You can download our demo which performs this operations and monitors real time and historical datas on the chart. You can find the instructions to give such service by here:

Open the project named Example Project. The database hasn't been created yet. Click Save As and save. Database will be created.
