In my opinion, this is a big issue. Is it not possible, that you communicate internally the extended enumeration to the MES department, so they can extend there specs, especially with the new commincation with OPC UA. We have to avoid too many applicationable solutions and define a standard of our data. Little example, I tell my customer which possibilities we have with the WorkingCode and we choose Check_the_checker to use. After integration and testing the MES, we only see the number. Now I ask the collegue from MES why, the answer is not I can integrate this, the answer is, WorkingCode from spec is only until 15, that's what we can use. Explaining the customer the situation, he cannot understand, why my standard is different to the MES one. I think, we should have a common data base in OPC UA and use the Input and Output Data for special things, if needed.
