Process Control
Process control requires a thorough understanding of the chemistry, mechanical and electrical elements of environmental, energy and industrial systems, including normal operation, emergency operation and potential incidents such as explosions, fires and spills. A thorough knowledge of building, fire, OSHA and EPA codes and regulations are required to design control systems so that the systems are employee-safe, comply with regulations and adequately alarmed.
Htec has extensive experience, gained over the years, of many industrial systems, including food & beverage, auto, steel, plastic molding and general manufacturing, plus water & wastewater, air pollution control, hazardous chemical storage, small packaged boilers to large coal-fired boilers.
Selecting the proper instrumentation, controls and programs are simplified once a comprehensive understanding of the industrial process control system is understood and defined.
Control Systems
Htec incorporates Allen-Bradley, GE and Siemens PLC hardware and software into integrated control systems coupled with Wonderware, Rockwell Automation and Siemens HMI software.
Control systems have to achieve three primary objectives:
- The system must precisely achieve the control and monitoring objectives of the client.
- KISS – Keep it Simple Stupid. The control logic and program must achieve the objectives as simply and direct as possible.
- Reliability – Any control systems must be online 24/7, day after day. This means the hardware and software must be thoroughly tested and highly reliable. Many times proprietary software has not been thoroughly tested.
- The system must provide appropriate alarms to the right persons, whether visual, audible, computer, text messages, e-mail or web-based.
