• Reduced errors – With clear visualization and guidance flows on the HMI, operators will make fewer mistakes.
• Increased productivity – Automation monitoring allowed processes to be controlled, freeing time from labor or allowing an operator to crank out higher quality output.
• Safety and compliance – HMI alarms and alerts connected to devices allow for real-time monitoring and response to critical non-conforming event, to protect workers and assets.
• Integration with advanced systems – HMI is designed to act or respond to sensor data or user input. 

HMI development tool selection is a crucial aspect of designing cost-effective, user-friendly, and future-ready HMI solutions. The choice of tools affects the operators’ day-to-day interactions with the machines. Careful HMI development tool consideration can lead to better performance, scalability, and usability.

To summarize the major considerations:

• Compatibility with Hardware and PLCs – Look for tools that can openly connect with different controllers, AMS’s, and industrial devices.
• Ease of Use –  user-friendly platform with drag-and-drop design, templates, and libraries can actually help to reduce engineering time and time spent on training.
• Scalability – Ensure that your tools will allow for expansion so that companies can add new HMI components as they grow their operations and also integrate with IoT platforms.
• Connectivity – When looking for tools, check not only that it can adhere to industrial protocols; for example, Modbus, OPC UA, and Ethernet/IP, but also your desire for cloud and remote capabilities.
• Customization/Flexibility – The ability to construct custom dashboards, find alarms, or make workflows is vital to the effectiveness of a man machine interface to ensure it meets specific industry sectors.
• Data-Database/Analytics – There is strength in having strong tag databases, as well as some data logging and reporting capabilities to ensure businesses can generate valid analytics for process improvement.
• Cost and Licensing – Evaluate costs associated with different licensing adjustments, pricing, upgrade options, and maintenance costs that can significantly impact affordability.
• Vendor Support/Updates – Make sure there is technical support should issues arise with the tool, and ideally understand what your update plans look like to keep systems up to date and secure with new technology.

If businesses take the time to evaluate these criteria, they can choose HMI development tools in a way that helps them prepare for either the economy’s or just the demands associated with Industry 4.0.
