Output of passivated data (substitute values) in case of error
The safety function requires that for passivation in the safety-oriented channel in the
JHG-PROFIsafe
module, the substitute values (0) are used in the following cases instead of
the cyclically output values. This status is indicated via the
F-Periphery-DB
with
PASS_OUT
= 1, see below.
●
at start-up of the F-System
●
in the case of errors in the safety-oriented communication between F-CPU and measuring
system via the PROFIsafe protocol
●
if the value set for the
Window increments
under the
iParameters
is exceeded and/or
the internally calculated PROFIsafe telegram is defective
●
if the permissible operating temperature range, as defined under the corresponding article
number, is fallen below or exceeded
●
if the measuring system is supplied with >36 V DC for longer than 200 ms
●
if the measuring system is disconnected in RUN mode, the F-Host is reconfigured and the
measuring system is then reconnected
9.2
F-Periphery-DB
For each F-Periphery, measuring system and digital output module, an
F-Periphery-DB
is automatically generated during compilation in
HW Config
. With
reference to the generated safety program, see chapter 8 “Safety Creation – Configuration
Example“ on page 54, this is block
DB1638
for the measuring system and
DB1639
for the
digital output module. The F-Periphery-DB contains variables which can be analyzed in the
safety program and can or must be written. An exception is the variable
DIAG
, which may only
be analyzed in the standard user program. Modification of the initial/current values of the
variables directly in the F-Periphery-DB is not possible, as the F-Periphery-DB is
know-how-
protected
.
The variables of the measuring system F-Periphery-DB must be accessed in the following
cases:
●
during operator acknowledgment of the measuring system after communication errors or
after the start-up phase
●
during execution of the preset adjustment function
●
when analyzing whether passivated or cyclical data are output
●
if the cyclical data of the
JHG-PROFIsafe
module are to be passivated depending on de-
fined states of the safety program, e.g. group passivation
