STL simplify some code

Hi,

I need to trend some data in WinCC, so I wrote this:

A M 69.0
JC HI
L 0
T MW 100
JC end
HI: L 1
T MW 100
end: NOP 0


Can this be simplified ? As allways, I want to learn to write shorter and shorter

Is it a good manner to trend this in WinCC ?

The code you have written could be done like this:

tnx

tnx

Combo,

I don't see the need for even a single line of code in the PLC program when I want to trend data in a SCADA system. I don't use WinCC myself because I'm kind of a Citect addict when it comes to SCADA, but I'm sure WinCC can trend a boolean variable as well as Citect can do it.

The only way you really need PLC code for the SCADA system is when you're packing data into a single consistent block to optimise the datatransfer.

Kind regards,

I agree with jvdc. You can configure the tag in WinCC as being logged per your specified data log criteria.
Best of luck

Hi

I had some problems for monitorring a boolean, but what you're saying is true, I had some adressing mistakes.

Thanks
