184 EZware5000 Series Programming Manual

1010-1007, Rev. 10

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.

This feature is not available on the X-models (HMI5104XH, HMI5121X, HMI5150X).

Disable Upload Function

Activate the Disable Upload Function in the System Parameter settings (Edit > System Parameters > System Setting

tab). Alternately, you can set LB9033 in the local reserved memory of the HMI to disable the upload function and

prevent a project from being uploaded from the HMI.

 The HMI must be rebooted after downloading the project in order for the Disable Upload Function to take effect.
