Project Protection
Enable Project Protection in the System Parameter settings (Edit > System Parameters > General tab). Use the Project
Protection feature to set a unique password (Project key) in the project that will cause the project to run only on
specific HMIs that have a matching password (HMI key).
A developer can set the HMI key in the reserved local memory of the HMI (LW9046 configured for 32-bit unsigned
numeric format). This value is stored in non-volatile memory, and once it is set, the value is hidden and cannot be
read using a numeric display. In this way, only HMIs with the correct HMI key will be able to run the project. If the
Project key does not match the HMI key, local bit LB9046 is set and the driver is disabled and will not communicate
with the PLC.
 The HMI must be rebooted in order for the HMI key setting to take effect.
