How to Enable VNC on the Basic HMIs
Tags: FAQ Remote

The Basic Series HMIs now support VNC (EBPro v6.03.02.257 or later). Since the B-Series do not have the VNC tab in the System Settings window to enable VNC, it needs to be done with System Bits and Words.


LW-9530 to LW-9533 are used to store the VNC server password on the HMI in ASCII format. The easiest way to set the password is to place an ASCII Input object on a window where the operator can enter the password. If you enable "Password from project" in the System Parameters > Remote tab, then you don't need to enter the password with LW-9530 through LW-9533.

A Set Bit on the Common Window assigned to LB-12092 can be used to enable the VNC server. A Set Bit on the Common Window assigned to LB-12093 can be used to enable the Multi-Connection.

Note: LB-12092 must be turned OFF before LB-12093 can be toggled ON or OFF.
