Hi Frink,

Many thanks for your response.

We are already using this solution to get the data from a small part of our factory as a trial.

However, we need to integrate other areas of the plant, and if we go with this solution, a lot of programming will be needed. For example, we had to construct the big command string ('insert into PLCDATA_1 values (7,8, 9)') with real-time values from the field. Also, there is only one trigger to execute the command, and we need to update one table in the database every minute and the other two tables on value change. So, we had to develop queuing logic to prioritise the command triggers.

With more data to integrate, it will become more complicated very quickly. Also, if this solution succeeds, our management is looking to roll out this to multiple factories all over the globe. So we are trying to make it as easy, standard and scalable as possible, and that is why I came up with the idea of WinCC runtime and VB script solution so that we can run the multiple scripts independently with scheduled tasks or separate triggers.

As per my understanding, we can run WinCC RT Professional as a service but not WinCC RT Advanced.

Kindly let me know your opinion.

Thanks & Regards,
Parag.
