Relevant only on workstations whereReadOnlyStation is set. Does not apply otherwise. A full discussion is provided in the topic, Read-Only Workstation.
This is a bitwise value that controls which application privileges are enabled at a read-only workstation. Operators signed in at that workstation must also possess each enabled privilege. This mask does not grant privileges to those who do not otherwise possess them. See also: StationMaskSys
If creating a StationMaskApp, you are advised to set the workstation property to match the name of the read-only station where it will be in effect. There is no default value for StationMaskApp.
Default:
Section: <SecurityManager-Admin>
Application privileges are numbered starting at 16, as shown in the Privileges dialog (Protect Pages and Output Tags) when Show Privilege Numbers is selected.
Bits are numbered starting at zero, and reading from the right to the left. Therefore, to discover which bits to set when creating StationMaskApp, you must subtract 16 from every application privilege as shown in the Privileges dialog. (Privilege 16 is bit 0, privilege 17 is bit 1.)
Using the StationMaskApp property to enable an application privilege that allows authorized operators to write through a protected I/O tag will have no effect. Read-only stations cannot write to I/O under any circumstances. Any privilege to allow I/O writes is meaningless at a read-only station.
