Setting Symbol Access
Overview FactoryCast Configurator sets default access for each symbol (variable) as you
add it to the namespace, based on your selection in the Default Access Settings
dialog.
This section discusses security considerations and describes two ways for you to
modify the security setting for a symbol.
Two Levels of
Access
Each symbol (variable) may be write-enabled or read-only.
l Write Enabled means users can modify the symbol value after supplying the
write password.
l Read Only means users cannot modify symbol values, even after supplying
the write password.
Using the
Checkbox to Set
Access
Select or deselect the checkbox in the Write Enabled column of the Symbol
window.
l A checkmark means the symbol is write-enabled.
l A blank checkbox means the symbol is read-only.

CAUTION
CHANGES TO SYMBOLS MAY RESULT IN CHANGES TO YOUR
APPLICATION
Be careful about which symbols (variables) you allow to be modified online, and be cautious
about who has permission to modify them. Unauthorized or incorrect changes to symbols
may change the behavior of your application in ways that may be undesirable or even
dangerous.
Failure to observe this precaution can result in injury or equipment damage.
