Going Forward
During the initialization phase, in the NW_INIT state, all write assemblies (e.g. the instances of the assembly mapping object with type“write”) will be remapped to the write process data area. For this to happen, the device will issue the Remap_ADI_Write_Area command to the application data object in the host.
See the appendix about “Runtime Remapping of Process Data” in the Anybus CompactCom 40 Software Design Guide for more information.
When the network has been initialized, the device transitions from NW_INIT to the WAIT_PROCESS state. When the device receives a forward open request, the producing/consuming parameters in the request are verified and matched against the EtherNet/IP Host Object instance numbers (producing/consuming)
If the verification is successful, the read process data is remapped and the device transitions to the PROCESS_ACTIVE state. The I/O connection will then be established, and data can be exchanged over the network.
