Could someone please clarify, I presume that the note means the tag access section of the policy is meaningless if running on a single gateway (edge in this instance).
Does this mean if there is a remote gateway on the network that access to tags can be controlled through the policy when connected to the local gateway?
Is there any way to control access to prevent a certain zone from being able to edit tags if using only a single gateway?
If you have an ignition gateway connecting to your devices, and a second using that gateways tags you can limit access in the security policies.
If you want to read/write to tags on the same gateway this policy won't affect it, you need to configure the security on the tags themselves in the designer. See here: Tag Security Properties | Ignition User Manual
