} Evaluation in the user program
One bit from the diagnostic word can be linked further within the PNOZmulti 2 user pro­
gram. The user selects a bit within a diagnostic word and polls it. An LED can be driven
in this way, for example.
} Evaluation using PVIS expanded diagnostics
The bits of a diagnostic word can be configured for PVIS expanded diagnostics in the
PNOZmulti Configurator. A "Safety Device" diagnostic type is assigned to an element. It
contains the diagnostic word as an event message. An event message including rem­
edies (actions) is defined in the diagnostic type for each event, i.e. for every potential
element state. The event messages and actions can also be supplemented through ad­
ditional information, which is helpful during diagnostics (equipment identifier, location
description). The event messages can be displayed on the PMImicro diag, for example.
INFORMATION
Detailed information on PVIS expanded diagnostics can be found in the
PNOZmulti Configurator's online help.
} Evaluation via the RS232/Ethernet interfaces
The diagnostic word is requested via the communication module using the element's ID
(see also Communication modules [ 26] ).
} Evaluation via a fieldbus
The diagnostic word is requested via a connected fieldbus module, via the element's ID
(see also Fieldbus Modules [ 13] ).
