Locking Active<br />

If selected, this input field can be locked during runtime. A locked input field is displayed but<br />

cannot be highlighted or accept new input.<br />

Locking only affects the input field, not the connected variable. Another input field on the<br />

same page can allow a different value to be written to the process variable even if this field is<br />

locked.<br />

The other options under this tab can only be enabled when this option is selected.<br />
