SCADA/Programmable Controls
ArcSine Engineering has considerable experience in planning and designing programmable systems for process monitoring and control. Most of ArcSine's process projects utilize programmable control, including programmable logic controllers (PLC's), remote terminal units (RTU's), personal computers (PC's) or larger platforms, and combinations of the elements above in supervisory control and data acquisition (SCADA) systems. Arcsine's projects include skillful integration of new controls with existing controls, with special attention to construction sequencing to maintain facility operation. Following are sample projects:
