Hi,  
I have 4 tags which are instances of the same User Data Type. One member of the User Data Type has a script attached to the Value Changed Event: this script will access a MS SQL Server database through the default database connection, that I defined in the gateway configuration. My question is: if the 4 events are fired at the same time, do I need to synchronize the access to the database from the 4 tag events scripts or is it Ignition itsself that do it for me?

Thank you in advance,  
regards

You don’t need to manage concurrent access to datasources.
