I'm trying to generate an FMU functioning as an Interface between simulated components (e.g. PLC´s) and a OPC UA server. My question is, if I´m trying to use this FMU for example to simulate an EtherCAT connection between these two, is there a maximum of possible in- and outputs?
I have a Code that hands me the nodes from the OPC UA Server already, but that are already a few hundred...
The FMU Specification 2.0.4 section 2.2.7 Definition of Model Variables (ModelVariables) and the FMU Specification 3.0.1 section 2.4.7.1. Static information both have a diagrams claiming that model variables are indexed from 1...∞.
Therefore, to adhere to the standard, FMI implementers should support the maximum number of variables possible in their environment. Which is most likely the largest integer they can use.
