Profile Properties that Affect Access by Third Party Applications
The properties in the Browsing tab control which variables a client application (including third party applications) can see when browsing variables exposed by PcVue. In order for an application to access a variable, the user authenticated on the API of PcVue, must have the corresponding browsing level right in its profile. Show picture.
At the time of writing, browsing level rights are applied by the following interfaces:
- OPC clients browsing or accessing OPC items corresponding to variables via PcVue’s OPC server when OPC-Security is enforced.
- Mobile apps: TouchVue and SnapVue.
- Third-party applications using the Web Services Toolkit interface.
In particular, it is a way to control what variables a user can browse when using Dream Report as either an OPC client or a Web Services Toolkit client.
This feature is intended to encourage more secure practices. Interfaces used to access the variables of PcVue are system boundaries, which it is advisable to secure.
