The FDA requires drug manufacturers to follow strict cleaning guidelines. According to the FDA, any equipment a manufacturer uses during drug production must be “cleaned, maintained, and, as appropriate for the nature of the drug, sanitized and/or sterilized at appropriate intervals to prevent malfunctions or contamination …” This is why drug manufacturers clean their batch process tanks at regular intervals.

On Friday, August 25th, Hurricane Harvey hit the South Texas coast. Consequently, the storm front struck our new manufacturing and warehouse building in Katy, Texas. High wind from a hurricane tornado damaged our roof structure, pulling air handling units from the roof and allowing water to enter the building.

Process automation plants using industrial HMI often place the equipment in remote locations in the field, away from the process control room or maintenance stations. For busy plant personnel, it's much easier to be able to configure these remote monitors from a centralized location or even off-site remote location. In addition, maintenance and technical support for the daily HMI operators can now be done remotely without needing to physically stand in front of the screen, which is often difficult and time-consuming (pharmaceutical clean rooms, large refineries for example.)

When installing a purged control panel or industrial HMI in a hazardous location, power supplied to the control panel must be regulated so that components are not energized before the panel is protected by a purge cycle.

What Is the Difference Between Zone 1 and Division 1?

A Zone 1 / Div. 1 industrial monitor must meet the requirements necessary for operating in the presence of ignitable concentrations of gases, vapors, or dusts that are likely to exist, either continuously or intermittently, under normal conditions.  That said, the certification requirements vary according to where you will be using your equipment.

Process challenges that lead to system integration

When industrial workstations are located in a hazardous area, you often need to invest in training for qualified personnel who must comply with safety guidelines as well as deal with the physical layout and restrictions of facilities that include hazardous areas. Investing in equipment that likewise meets the challenges of the hazardous area is a must.

It's rather time consuming to walk back and forth between the production area and the control room to access a local HMI system. It's much more efficient and convenient to monitor control room functions locally, right inside the process area, using properly certified equipment that is rugged enough to withstand the tough environments external to the control room. Being closer to the process empowers you with greater control and monitoring capabilities in real time.

Our remote monitor thin clients come in a variety of sizes and flavors. The standard remote monitor (RM) is designed for easy startup and maintenance. The ACP ThinManager RM is designed for users with ThinManager as their thin client management tool.

KVM Extender Selection Criteria

Industrial keyboards, video monitors, and/or mice are usually located within 6 feet or 2 meters of the source PC or thin client. However, there are times when you need to mount an industrial display farther away from the source signal—sometimes in a different building or type of location, such as outdoors, on the process floor, and/or in a hazardous location.

Customers often want to know what exactly is a Class I, Div. 2 industrial display. Or, what choices there are for HMI visualization and machine control in a Division 2 area, and if a purge system is required. The answers depend on what is connected to the display, and the type of HMI software. This information helps you decide whether to look at an industrial monitor, a panel PC, or a networked monitor via thin client or KVM back to a host in a control room.
