‘What is the maximum data capacity that the OPC link can handle?’
In terms of mean data reads and data writes per second, running at real speed between DeltaV Simulate server and a third party client through OPC.
I am aware that data is only read / written depending on value relative to tolerance.
I am also aware that the bottle-neck is usually network related (using GB rather than 100MB switches).
Any suggestions to how this can be quantified? or measured on a system.
I also had some discussions previously relating to whether there was a flag to ensure whether everything that needed to be sent had been received.
So (I understand) having a watchdog signal between DeltaV and the third party client is not a definative test. As it may not be the last / lowest priority signal scan.
