Minimize Data Transfer
IMPORTANT:
When you write to a tag, regardless if the data is the same or different, the system crossloads it, along with the used memory that is in the same package, during the next configured crossload time. For optimal performance, write to tags only when necessary. For example, do not write to tags for HMI reads faster than 2x the update rate.
- For data that is known to change frequently, we recommend grouping it all into a structure. You can then reference each member of this structure by using the alias functionality with only minor changes to the application programming. This can minimize the amount of data that is required to be transferred.
- Program sync points can be selectively turned off to reduce the frequency of transferred data. For optimal performance have as few sync points as the application allows.
For more information, see Configure Crossload and Synchronization Settings.
