I am using Ignition version 7.2.11-beta1 (b209), but the online documentation is insufficient for this version. For example, system.tag.read is unavailable (it seems at least based on the errors I am getting: AttributeError: instance of ‘com.inductiveautomation.ignition.common.script.ScriptPackage’ has no attribute ‘read’) and “system.tag.getTagValue” seems to work but it is not in the current online documentation: [inductiveautomation.com/supp … s/ignition](http://www.inductiveautomation.com/support/usermanuals/ignition)

Any help would be appreciated.

Isn’t there a User Manual link on the gateway? System \> User Manual?

Great! 😃 Wasn’t 100% sure if it was there in 7.2.
