7. Perform Distribution Design

This system configuration illustrates a distribution design of the ASM_MVCDL example in which the Model+View functions are located in a remote device named MODEL, the Control+HMI functions are in a local device named CONTROL; and the Diagnostic functions are in a local device named (surprise!) DIAGNOSTICS. Each of the MODEL and DIAGNOSTICS devices contains a TAGS resource that uses the Tagged Data Design Pattern to provide the functionality defined in the table below.

Resource Function
MODEL.TAGS
  • Gather sensor data and publish it remotely.
  • Receive remote actuator data and publish it locally.
DIAGNOSTICS.TAGS
  • Receive remote sensor data and publish it locally to both DIAGNOSTICS and CONTROL devices.
  • Gather actuator data from the CONTROL device and publish it remotely.
