There is a range of HMI Data Variable Types you can use define an expressive data model e.g Numeric Data Variables.

“PLC-First” Strategy

Import and Augment Existing PLC Data

Use this strategy when…

• a solid data model for the PLC already exists.
• you don't need to adjust your HMI model to reach desired states and outcomes within your HMI.

“HMI-first” Strategy

Define HMI Data First and Link to PLC Later

Use this strategy when…

• the PLC and its data model have not been defined, yet.
• you need design the data model together with PLC experts of your team. HELIO can then be a communication tool for quickly sketching out the data model and using it with the help of the Placeholder Mode inside the Content View.
