Processes combining regulatory and discrete controls (such as compressor control in upstream, mold-level control in the iron and steel industries) require highly reliable high-speed analog controls to meet customers demands. In these areas, PLCs or DCSs are installed depending on the process. However, not many PLCs have a highly reliable dual redundant configuration and DCS-like maintenance ability. FCN/FCJ provides complete redundancy in control, field and OPC networks and "One Click Online Download," similar maintenance ability to DCS.

Yokogawa NCS Stardom best suit Yokogawa DCS CENTUM CS 3000 R3 to smoothly integrate both DCS and NCS data onto the CENTUM CS 3000 R3.

 

Even in the the conventional regulatory control area, the high-speed and highly reliable PLCs are more required than ever as the functionality and operation speed of the equipment improves. For examle, a mold-level control requires the high-speed PLCs to be adapted to the faster casting speed.
