Configuration instead of planning, this maxim has been a key factor for the continuously growing requirement of accelerating product development processes since introduction of the Eplan Engineering Center (EEC). With the coupling of EEC and Eplan Pro Panel Professional to form a integrated solution, the future-orientated technology of configuration is now also moving into control cabinet and switchgear manufacturing. The main advantage for users: configuration is based upon predefined rules and standards. All of the knowledge relating to components, modules, mechanical forms and electrical requirements are deposited in the system. This considerably improves the quality of documentation. The optional connection of Eplan Pro Panel to the EEC is available with the new release of the Eplan Engineering Center, which will be appearing at the Hannover Messe.
