The navigation diagram shows all the lists headers and parameters that can, potentially, be present in the controller. In practice, those actually present will vary according to the particular configuration choices you make.

Changing the passwords

There are TWO passwords. These are stored in the Password configuration list and can be selected and changed in the same manner as any other configuration parameter.

The password names are:	‘ACC.P’	which protects access to Full level and Edit level
	‘cnF.P’	which protects access to Configuration level.
