Dear Jesper,
In my country among other very important things there is a lack of an industrial modernisation mentality. Combine that with the fiscal crisis we are going through and you realise how little opportunity is out there for retrofits.
In most of the cases the mentality is to never change a system if it operates. Then comes a time where the whole production collapses and managers seek explainations on why this the production was not modernized in time (when it was them complaining that they dont have a budget).
Our Company is only involved in S5 projects when they are migrated to modern control systems.
However I can understand other colleagues & companies from countries like mine, where there isn't much buisness opportunity, and they get involved in S5 or other obsolete system projects. They are just trying to make a living out of it. I don't believe that any professional chooses to support an old "finished" system rather than installing a brand new top of the notch PLC.
Regarding the need for IBH Link S5++ I think I mentioned it, but it is a good thing to mention it again.
Regarding the responce time, I quote this from the IBH Link S5++
manual:
- If optimization can fully work, refresh rates from 200-300ms are realistic. If there is no optimization possible, reading may take a few seconds. An average refresh rate of a second should be a good point to start.
I am not saying that IBHsoftec's is the best solution, but it may be a solution.

If you transfer data from the S5 to the S7 keep this in mind (
Very well typed here):
DB addresses are word oriented in S5. The DW0 in a S5 is equivalent to the DBW0 of a S7. The DW5 of a S5 is equivalent to the DBW10 of a S7. All other addresses within DBs follow this logic.
S5 S7 DL 0 DBB 0 DR 0 DBB 1 DL 1 DBB 2 DR 1 DBB 3 DL 2 DBB 4 DR 2 DBB 5 oder
DW 0 DBW 0 DW 1 DBW 2 DW 1 DBW 4 ... ...
