HMI (Human Machine Interface) software is used to provide a graphical interface between an operator and a network of sensors and control devices deployed in the field. It can include the entire program for operating the SCADA system, including communications, or be an adjunct to a Master RTU (Remote Terminal Unit) that communicates to a deployed set of slave RTUs, but in all cases it is used to display data, alarms, and equipment status while providing for control of deployed devices.
SCADA software was developed for process control applications typically associated with large-scale industrial applications but WT generally deploys Events Software designed for ease of use in more limited systems typical to irrigation districts and large farms.
WatchTechnologies has worked to develop SCADA HMI specifically suited for Maritime and Water Management markets that brings this powerful technology to tasks of more modest size than the typical industrial setting. This savesprogramming time and money for our clients along the way.
HMI software is uniquely configured for each SCADA project.The objectives of the HMI operation are to provide clear images, efficiently generate commands and reports and communicate with RTUs in the field and remote operators. How efficiently HMI software can be deployed and operated depends on the complexity of the task and the nature of the HMI product selected.
Watch Technologies' HMI software can be managed and modified by the system operator. This feature makes a vast difference in the deployed cost of a program and certainly its maintenance since a field engineer may not be required to make typical changes or additions to a project.
