As stated in our previous post, FBx Historical Configuration and Log Retrieval Using ROC Protocol for SCADA and IIoT Remote Monitoring, there are some significant changes to the way FBx are set up compared to the older Flobosses.
One of the major changes between Flobosses and the new FBx flow computers is that the FBx meters now use DNP as their primary protocol. In order to stay backwards compatible with existing SCADA systems, Emerson provides an optional ROCTalk Protocol communication for the FBx meters.
This creates a new problem, however: if an installer wanted to connect the FBx to an existing network and poll it using ROC Protocol, they would no longer be able to use the Field Tools because Field Tools requires the DNP Protocol to talk to the device.
This post shows 2 methods to access the same device with multiple protocols.
