New Human-Machine Interface (HMI) to provide a complete gas and hazard visibility solution

Jul 02 2019 Read 297 Times

Crowcon has developed an HMI solution that creates complete system visibility. The solution can run alongside existing DCS/SCADA/PLC systems or mimic panels which are used to monitor wider system views, often incorporating other sensors including security, flow, smoke and fire.

Crowcon’s product manager William Allum explains, “This solution enables our customers to view data from multiple panels from one central screen. Due to the system having the ability to store alarm and event logs, users can quickly understand the symptoms of a problem as they view the information and identify the exact location.

Vortex and Gasmaster HMI employs license activated software operated from a dedicated touchscreen panel. As the system is modular, users specify the required number of input converters to link the number of controllers in their system. It monitors up to six Vortex panels or racks, or up to 10 Gasmaster controllers operating on one system, so either Vortex or Gasmaster.”

The display shows gas levels from all detectors from the chosen panel simultaneously and enables the user to easily adjust or test a system. It is now possible to see the details of each controller within a system, including alarm indications, as well as the complete configuration and location of each gas detector.

Users can also see possible trends within the alerts. For example, an alarm in a specific location may be triggered on a regular basis. This is due to the development of a one-hour ‘trend visibility by gas’ function.

Crowcon HMI can be configured in various different setups with the options to connect locally, via a network or directly via HMI enclosure. The Crowcon HMI can connect with the controller via RS-485 MODBUS or ethernet cable which are capable of long distance connectivity.

The large multi-lingual display shows gas levels from all detectors simultaneously and enables you to easily adjust and test the system. It operates stand-alone or can interface with any alarm device and control system using a selection of outputs. All the information you need about your gas and fire detectors is available, at a glance on Gasmaster’s compact, versatile and powerful gas detection control pane. Simple to operate with a comprehensive selection of input and output functions.

Vortex’s flexible control package can be customised to meet site requirements without the need for extensive cabling. The rack and panel comprise the essential input, output and controller modules which are mounted on a DIN rail. An optional display module is available in panel-mounting and 19" Rack formats. This configuration can be incorporated into a variety of specialist enclosures, such as 19" format or those with high ingress protection.
