800xA HART connect error
We need to read the PV with the transmitter through the HART protocol. We have a problem with connection a HART device to the 800xA (AI845, AI895). We are trying to connect to the transmitter, but the connection is not established. Find attached the screenshots. Tell me what could be the problem.
Hi, what do you mean read the PV?
Hart with the S800 is used for advanced diagnostics from the IO boards and the instrument. You can read the PV on demand but not cyclically, for this you would need the S900 IO.
Anyhow start first with CBM, check that the controller has enabled tool routing. Then as I see by the pics the device object type is installed and instantiated. First check in CBM if you can see the PV.
Then try to configure the OPC server in PPA (fieldbus aspect) and finally enable the communication. Then you can call the observe (on device aspect) here you can see the PV by Hart.
Finally you can upload the asset monitors checking the configuration of the asset is ok. Then your assets should show their correct status.
