Does anyone have experience with application with many datapoint functions
We will need to optimize the communication to the PLC so that we reach the desired update times.
Our PLC (1500 series) will be using the S7+ protocol. This means that we have the following options to reach an optimal communication response:
* Use subscriptions
* 'Pack' the bits into (d)words and use dp functions to extract the bits from the word into dp elements
Does anyone have experience with a WinCC Oa database, running on one server, with (lets say) 200.000 dp functions ?? (Please note that only a low amount of signals will actually change. I'd expect a small amount of changes per second. We have smoothing and time-delays in the PLC's)
Thanks for your answer
share the fun
As long as the input signals are not changing they are not causing any load. A high number of dp functions will only increase the memory usage of the Event Manager.
