What is the main goal of Multiprocess ?

When we select multiprocess we have any troubles (each process has personal local variables and etc)/ Which bonus we have when we select multiprocess ?

In other SCADA systems (for example WinCC, InTouch, RSView32, iFix, Proficy) we have not anything like multiprocess/single_process in Citect .....

  • Hi Anton,
    With modern computer hardware becoming more parallel processor capable, it was a logical step in the architecture of the product. It just makes sense to run each sub-system on its own process to make the most of available resources and give more capacity to each function.
    With regards to local variables each residing in their own process, this is by design. You can engineer or properly configure your SCADA system to work they way you need it to, e.g. via standard variable tags (can still be set to Memory - but truly distributed across the entire system).
    So short answer, to keep up with modern tech and unlock more capacity and performance.
    Please tell me which SCADA system on the market offers the performance and scalability with n-level device redundancy that Citect offers.
