Menu navigation: Overview → Device Information → Security and Simulation
An automated task procedure called a Method guides you through write lock setup. Write
lock permits you to configure, enable, and disable the various write lock options. You can
implement write lock can be implemented as a hardware lock or a software lock. If you
implement it as a hardware lock, the position of the hardware lock switch on the
transmitter electronics board will determine if device writes are permitted. Hardware write
lock is typically used to prevent writes from a remote location. Software write lock is used
to prevent local or remote writes unless the write lock is disabled.
When the write lock procedure is initiated, it first informs you if write lock is currently
enabled and if it is configured as hardware or software write lock.
If hardware write lock is enabled, you must set the physical switch on the electronics board
in the unlocked position to enable changes, including changes to write lock, to be
permitted.
If software write lock is enabled, follow the on-screen instructions to enable changes.
Select hardware or software write lock by clicking the radio button next to the desired
option.
