Ensure Correct Date and Time Settings on All Devices
Juggling with dates and time can be a real pain, especially in a client-server architecture with multiple computers being involved.
So, make sure all the computers involved are set up correctly:
- Backends (aka your PLC)
- The time on the PLC must be set correctly, including the time zone in which the system clock is running.
- Timestamps from the PLC must always include an offset specification (e.g. UTC or UTC+2).
- Computers Executing the HELIO Runtime
- The time on the computer that is executing the HELIO Runtime must be set correctly as well.
- Computers Executing the HMIs
- Finally the time zone on all the computers running the HMI in the browser must be set correctly.
