Parameterization Of The Controllers - WAGO I/O SYSTEM 750 750-833 Manual

3.7 Parameterization of the Controllers

Before a data exchange can be performed between master and slave, a
parameterization is required in addition to configuration.
The extended parameters (Extended User_Prm_Data) are provided via GSD
files as selectable text in the configuration programs.

Meaning
Restart of the terminal bus following a fault,
such as, for example, no termination module
following
an interruption of the supply
immediately after overcoming the internal bus
fault
The diagnostics information of all I/O modules
with a diagnostics capability, for which the
diagnostics is released are
transferred to PROFIBUS DP master
not transferred to PROFIBUS DP master
Word or double word oriented process data, is
transferred to PROFIBUS DP master in:
„Little Endian Format"
„Big Endian Format"
In the case of a malfunction of the
PROFIBUS DP communication the status of the
connected output periphery can be influenced in
various ways:
The process data exchange on the internal bus is
stopped, all outputs drop out after a module
specific monitoring time of 100 ms
all outputs are immediately reset
all outputs maintain the last status before the
malfunction
all outputs switch a parameterizable substitute
value
PFC takes over the control via the output image
In the event of a malfunction of an internal
communication between field bus controller and
I/O modules, such as, for example no
termination module,
the data exchange with the PROFIBUS master is
stopped.
the input information is set to zero
the input information prevailing before the fault
is maintained
Using binary I/O modules containing redundant
data on the internal data bus side,
all data of the internal data bus image are
mapped in the PFC image
only the relevant data, that are connected to the
periphery (no diagnostics data), are mapped in
the PFC image
When projecting PFC modules using the
PROFIBUS DP configuration tool, the modules
cannot be parameterized as "not being
connected"
can be parameterized as "not being connected"
