Performance

Simulation communication

Add array OPCItems as Advise from a OPC Client.
It is measured reading time from added OPCItems. Communication performance is defined as average time of ten times measurement.
This time means to read the value of a continuous area of the device.

In case of continuous integer array tag , it is possible to get max 300 points per sec.

Comment

*Graph displays average time of ten times measurement.(1point = 1word)
*The result only means our examination, it doesn't guarantee performance.
