3.6.8 SECURITY PANEL Screen

The control provides wide-range data security service. The picture shows the SECURITY PANEL screen. When the general security gate is open the other security gates have no significant role, thus all actions listed on the screen can be executed even if the symbol . is displayed beside the action.

If however the general security gate is locked, i.e., the symbol . is seen beside the caption the ac- tions, beside the name of which lock symbol . is displayed, cannot be executed. If e.g. pa-

rameters are to be edited and this action is locked display . in the 7th field of status bar warns

us that this action is closed in case action menu button is pressed on parameters screen.

The general security gate, the DNC channel, the parameters, the PLC program and the service operations have

generated code, or PLC key,

that means that in case of opening, either as an answer to the digits displayed by the control another number generated from those digits must be given, or the security gate can be opened in the open (enable) state of the key switch mounted on the machine.

The other functions have

fix code, or PLC key,

that means that these functions are opened either with a code given in the below table or in the open (enable) state of the key switch mounted on the machine.
