Structure of the diagnostic word
The diagnostic word has 16 Bits:
Bit 15 14 ... 2 1 0
If the diagnostic word = 0, the output of the respective element = 1. The element was ena-
bled. (Exceptions: On various function elements the states of the inputs are evaluated (see
Chapter
Compilation of the diagnostic words [ 131] ).
Otherwise, at least one of the bits 0 ... 15 of the diagnostic word is set and can be evaluat-
ed,
e.g.: Bit 1 =1:00000000 00000010
Key: Safety gate has been opened
Evaluate diagnostic word
} Evaluation in the user program
One bit from the diagnostic word can be linked further within the PNOZmulti 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 reme-
dies (actions) is defined in the diagnostic type for each event, i.e. for every potential el-
ement state. The event messages and actions can also be supplemented through addi-
tional 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.
