How I can simulate process variables (Flow.temperature,…) in Visual Basic?

[PaoloPemi]

which is the scope of your project ?

Many software applications include interfaces to VBA, 

one is Excel but there are process simulators (both commercial as Aspen and / or open source as Dwsim etc.), process libraries (as Prode) etc.

It depends from your specific application...

Hi paolopemi,
Simple Excel VBA for process control philosophy like control level in steam generator or any process variables.

[PaoloPemi]

you can simulate a generic PI / PID controller in Excel (google to find examples),
define a transfer function for your system and Excel will calculate / show the results,
see for example
