OPC DA Client for plant visualization via Standard Web Browser
https://support.industry.siemens.com/cs/document/24272005/
This entry illustrates a simple way of visualizing S7 variables on a web browser using the example of a weather station. For the solution of this task, the OPC server of SIMATIC NET is used.
This entry contains an OPC HTML Generator, which depicts the OPC variables on an HTML page and updates them cyclically. The desired variables are configured on the user interface, a respective dummy is defined and a template generated. This template serves as a templated for the HTML page.
For the settings of the template there are two options
Automatic generation by the OPC HTML Generator
Programming according to own requirements.
