How does HELIO determine the license limits?

HELIO considers four factors when calculating the limits for the active license in your Runtime:

Number of projects

This refers to the total number of projects you can create using the HELIO IDE.

Number of data sources

The number of data sources, or PLCs, that your runtime can connect to using the Data View of the Project Editor.

What's included in the count?

What's not included in the count?

  • Data Collections will not be counted. You can have as many collections as you like.

Number of variables

When creating your HMI and defining its data model using the Data View of the Project Editor, it is important to consider keep two limitations associated with runtime licenses in mind. This maximum number is available for each project of the runtime. So the number of variables do not add up across projects. Each projects starts with a fresh count.

What's included in the count?

  • Each HMI Variable in you project will be counted as one.
  • Each HMI Variable that are part of a List Item Blueprint will be counted as one.
  • Each HMI Data Method will be considered as one.

What's not included in the count?

  • Lists will not be counted.
    • Only the variables in the List Item Blueprint will be counted as one.
    • The actual length of the list is not important for the calculation.
  • Directories will not be counted.
  • PLC Variables will not be counted.

Number of connected clients

Every browser that connects to your HELIO Runtime is considered a client. For example the browser on the touch panel right next to the machine. But also the browser on the PC in the shift supervisor's office.
