User Data Holding Buffer

The User Data Holding Buffer is a temporary storage location for user data that is written from a PLC using the Transfer User Data service. This buffer can be used to build up a large data transfer into the vision system, ensuring data integrity during a large transfer. When the Transfer User Data service is executed, the In-Sight Spreadsheet will not be able to read the data until the Set User Data service is executed. Once that service is executed, all transferred data will be accessible to the In-Sight spreadsheet. This mechanism ensures that the In-Sight spreadsheet is always accessing consistent data.
