Example:
Function Block Diagram - LOCAL_TO_UTC:
                         
                    
The LOCAL_TO_UTC function converts a date and time input from local time into Coordinated Universal Time. In the example shown above, the LOCAL_TO_UTC function takes the local time input and removes the local time settings to provide an output in UTC. In this case, the LOCAL_TO_UTC function takes the input time and removes 1 hour for the output (the local time settings are 1 hour in advance).
ST Program - LOCAL_TO_UTC:
The syntax for a LOCAL_TO_UTC function in an ST Program is:
Output := LOCAL_TO_UTC (Input 1);
Where Output and Input 1 are defined as variables earlier in the ST program. The Input 1 variable represents a Date and Time value.
