PROFINET BRINGS “NOTICEABLE BENEFITS” TO HYDRO-POWER

S7-414HGuangdong Qingyuan hydro-power station is among the largest stations of its type in China. The control system uses a redundant structure and is based on a SIMATIC S7-414-5H CPU as the master controller, with both PROFIBUS and PROFINET used for communications. By adopting PROFINET the customer was able to save a significant amount of cost by reducing the equipment that was needed. The S7-414-5H has a very fast cycle time, while the fast data transmission rate of PROFINET ensures reliable, real time communication. Currently, the whole system is running well. PROFINET brings noticeable benefits, not only because of the increased data transmission rate of 100M bps, but also because the installation of PROFINET equipment is very convenient. In addition, the diagnostics capability and PROFINET tools make the onsite commissioning task very efficient.  SIEMENS
