Alarm Management Best Practices for Safer Plant Operations

Supervisory control and data acquisition (SCADA) system alarms are a key tool for managing maintaining safe operations. However, the number of alarms generated can be excessive, overloading controllers and creating a significant safety hazard, making effective alarm management a necessity. 

The definition of alarm management centers around two major components — managing the notifications generated by the SCADA system and developing a program to analyze and continually improve the alarm system. In other words, reducing the number of false alarms and improving the management of real alarms to reduce controller load.

The Basics of MQTT-The Messaging Protocol for the Internet of Things

MQTT is a machine-to-machine  (M2M) and Internet of Things (IoT) open protocol standardized by the OASIS Technical Committee (www.oasis-open.org). The protocol is easy to adopt for a wide variety of IoT devices, platforms, and operating systems. Enterprise cloud platforms such as Microsoft Azure expose their IoT PaaS through MQTT. 
This blog post covers the core concepts of MQTT that are necessary for building M2M and IoT applications. It covers the basic terminology, along with a section on integrating MQTT with an IoTView HMI.

9 Signs Your SCADA Alarm System is Ineffective

Alarms are one of the most critical components of industrial operations and the primary means of alerting the control room operators of abnormal situations. Effective handling of alarms is crucial to the plant’s safety, productivity and profitability; however, many manufacturing facilities do not have a long-term, well-defined alarm management program in place. In most cases the approach remains reactive rather than proactive.

Read the post to learn about the top nine indicators of poorly designed alarm system and ineffective alarm management, and identify the ones that are present in your facility.

Choosing between InTouch Machine Edition Full Windows Runtime, Embedded Standard, Embedded Compact, and IoTView for your HMI Application

InTouch Machine Edition is an integrated development environment, which allows you to design, develop, troubleshoot, and maintain HMI applications and deploy them into different platforms (operating systems). Even though the development environment (and the application) is the same for any platform, Wonderware offers different runtime editions suitable for technical and commercial constraints on each platform: InTouch Machine Edition Full Runtime, Embedded Standard runtime, Embedded Compact, and IoTView runtime.
