In the past, there were conversion issues with using from simulations developed for the VIM to the DeltaV Simulate OPC drivers. Has this been addressed in MiMiC v3?
Yes, in MiMiC v3 the simulations are completely portable between different simulation drivers. In MiMiC v3 the models read and write data to simulated IO tags (SIO). The SIO tag directs the read or write to the appropriate IO assignment or fully-qualified data path using the SIO bridge services. To switch a process model between simulation for direct DeltaV IO and DeltaV Simulate parameters is as simple as stopping the simulation node, and re-starting it with a different SIO definition.
