A process control system for a fieldbus network includes field devices having function blocks. Some distributed control systems access the standard parameters of the function blocks but cannot access manufacturers' non-standard parameters. Such parameters are placed in shared transducer blocks in the field devices where they are accessed by an alternate system for configuration and for collecting and monitoring data. This enables use by the function blocks of both standard and manufacturers' specific parameters and enables function blocks with only standard parameters to facilitate non-standard inter-function block communication connections using the shared transducer block parameters. |
