- Recipe and parameter sets for hopper current, tank and hopper levels, fan speeds and temperature
Project Overview
KRS ICS designed, fabricated, and commissioned a dedicated motor and electrical protection control panel to safeguard critical plant equipment against overload, short-circuit, and fault conditions. The panel integrates ABB motor protection circuit breakers and a main SACE Tmax breaker with Danfoss VLT variable frequency drives for screw feed and water pump duties, all wired and labeled to clear safety standards.
Our Approach
A Siemens SIMATIC S7-1200 PLC with ET 200SP distributed I/O and SITOP power supply handles local control logic, while a Siemens WinCC Unified PC provides centralized supervisory visualization. An Ewon Flexy gateway was added for secure remote access, allowing our engineers to monitor performance and support the system without needing to travel on site.
