As one of the first, the municipality of the city Kaiserslautern in Germany, Stadtwerke Kaiserslautern, took the chance to benefit from an upgrade of their installed RTU211 base. The successful pilot project comprised the migration of one of the installed RTU211 to the new RTU511.
In only 30 minutes the actual replacement on site was done. Hitachi Energy provided the new communication unit (CMU) for RTU511 which replaced the old CMU to upgrade the hardware to the RTU511 and supervised the procedure which was carried out by the customer.
The existing configuration data of the RTU211 were prepared for the migration in advance with RTUtil500. Existing wirings were re-used so that the replaced parts were limited to the new CMU module and the housing of the migration kit. So for the customer it took only a few steps for the hardware replacement, whereas the gain in functionality and flexibility was outstanding.
The customer was very satisfied with the new RTU511. It does not only represent a lifetime extension of the installed system, but also provides a higher functionality and flexibility. Furthermore, the plus of functions will give the customer the opportunity to get more out of the established system.
