Hi everybody

I'd like to know if someone on the list have any experience working with Simatic software WinCC?
I have a system configuration( 4.01 version ) with more than 300 points (variables), and when I try to read these data, it becomes too slow. I mean that the system takes too much time to access for example to the historical trends, to the reports, to some calculus, etc. Can someone on the list help me?

- Try changing the comunication method of the chosen communication that You use. This is done by clicking right mouse button on the used communication (for example: Ethernet) and selecting properties.
- Try slowing the speed you use of the graphics that are tag related (if you are using 1sec chang all in 2sec).
- How much WorkMemory do You use? try at least 128Mbyte or more.
- Do you use a 417 CPU? probably not but this one has a Bug in the communications setting after power up is runs then on 6% in stead of 20%.
- How much time uses the trends and alarms. If fast then slow it (if using 1sec than change in more than 5sec for trends).
- How fast is your system? specially the harddisk? It is all Database related and needs fast responding harddisks, CPU's and lot of memory.

Just a few things to start with I hope. Good luck.

You can always goto the Siemens web site www.siemens.de for lots of more help.

A few weeks ago I was discussing the scalability problems of DP with a colleague, who told me about how he had a serious performance problem with WinCC using DP. He rang Siemens tech support who said "You should be using FMS for that much data". Kind of underlines the point really. Note: Reducing the DP speed would reduce the data
arrival rate and hence the number of things that get updated with each new data arrival.

I am an italian Automation Engineer who start to work with WinCC since last month and I think the system is very slow when start to access data. I use version 5.0, the new release with an option active (the archive). Now I can't help you but I would like have an e-mail address from you for exchange experiences, data and develops.
Siemens asks a pentium II cpu and and minimum 128 k of ram. I think this is the base system but I have pentium III and 256 k (I prefer safety) and this is probabily the first step to improve your system now.
