800xA 6.0 Foundation Fieldbus H1 ABB TZIDC Control Connection Bad Quality
On one of our clients Foundation Fieldbus Network we have configured successfully the communication between Control Builder's Application and the FF Builder Communication through a redundant CI860 communication module, but we still have a problem with the communication of Foundation Fieldbus OPC connection to the "Resourse", "Transducer" and "Function block" of the Fieldbus Device (ABB TZIDC Positioner).
Communication with all devices of the network is good from the HSE subnet through the TZIDC Fieldbus Device (LCV1201_FF object in control structure) but Control Connection Aspects of each block under the Fieldbus Device shows Bad Quality and does not accuire data from the instrument. Inside FF Builder in commissioning mode communication is successfull with the device and accepts all the changes from Control Builder's Application.
How can we solve this communication problem between FF OPC and the Fieldbus Device ?. All the service providers are in Service, everything looks good inside FF Builder.
OPC reconciliation, download of configuration to device is ok.
