Collecting fast update values from Infi-9
We have a customer with 800xA version 5.1 running on an older bailey Infi-90 system. We would like to collect data via OPC for loop tuning. To do this we need a 1 second collection interval with no exception reporting so that we can collect at minimum the PV, SP, OP of a loop.
There are a number of third party alternatives that can do this. However I cannot see how to do this with 800xA. All of the data is only available through 800xA with a large deadband and extremely slow update rate - which is fine for the HMI, but totally useless for tuning.
Any suggestions ?
