Hart multiplexer connect or asset management for cyclic data read
We are using S800 I/O in our project with CI854 as profibus master and CI840 as profibus slave. We have an independent asset optimisation server for accessing HART data. Plant is already running.
we want to control valve feedback in graphics using HART/Asset Optimisation.
We configured cyclic read of HART data via the "configure opc server" option and used property transfer to show the data on graphics, but the minimum update time observed was 60 seconds.
Is there any way to get a faster update time for HART data using the current setup?
Can we achieve a faster scan time using HART MULTIPLEXER CONNECT?
Is it possible to use a third party HART OPC server with a faster scan time and read the data via OPC server connection in 800 xa?
I am aware that a faster scan time is possible with S900IO but is there any way the same can be done using S800IO and a Separate HART MUX ?
Can it be faster, update rate of 3-5 seconds ?

Do not use P/H OPC server for anything else such as graphics other than Asset Optimization. Minimum update rate on P/H OPC server can be 30 minutes and it is designed only for AO as client.
You can use HART Mux and its OPC server and 800xA's 3rd party OPC connection possibility to achieve what you are looking for. I have done this in a plant and working good since 4 years.
