8.3 FL-net Profile
8.3.1 Device communication information classification
In the FL-net, the communications-related information about networked devices is classified into
three types as shown in Figure 8-9.
Figure 8-9 Device Communication Information Classification
The network parameters (A) are essential to the information setup for transmission.
The system parameters (B) are static parameters, which furnish management information for
identifying the networked devices. These parameters are divided into common parameters
and device-specific parameters.
The device communication input/output information can be accessed from remote networked
devices whenever it is needed for applications. This information includes dynamic
information, which varies with application operations and device conditions.
