The variable
IPAR_OK
is used to indicate successful execution of the preset adjustment
function. The process sequence for execution of this function is described
in chapter 10 “Preset Adjustment Function“ on page 80.
A precise description of how the variable can be analyzed in the event of a re-parameterization
of fail-safe DP standard slaves/IO standard devices can be found in the PROFIsafe
Specification from V1.20, or the documentation on the fail-safe DP Standard Slave/IO Standard
Device.
9.2.1.8 DIAG
The
DIAG
variable provides non-fail-safe information of 1 byte on errors that have occurred, for

9.3 Access to variables of the F-Perhiphery-DB
For each F-Periphery, measuring system and digital output module, an
F-Periphery-DB
is generated automatically during compilation in
HW Config
and a
symbolic name is entered in the symbol table at the same time.
The symbolic name is formed from the fixed prefix "F", the initial address of the F-Periphery
and the name entered for the F-Periphery in
HW Config
in the
Object Properties
, max.
17 characters.
Variables of the F-Periphery-DB of an F-Periphery may only be accessed from an F-Runtime
Group and only from the F-Runtime Group from which the channels of this F-Periphery are
accessed, when access is available.
The variables of the F-Periphery-DB can be accessed by specifying the symbolic name of the
F-Periphery-DB and the name of the variable: "fully qualified DB access".
It must be ensured in
SIMATIC Manager
, that in the
FBD/LAD Editor
in the menu
Options  Customize
in the
General
register the option “Report cross-accesses as error”
is not activated. Otherwise access to variables of the F-Periphery-DB will not be possible.
