Parameterizing The Spl--Sge Interface - Siemens Sinumerik 840D sl Function Manual

Connecting Sensors/Actuators
7.2 Connecting I/O via PROFIsafe
Parameter assignment:
Machine data $MN_PROFISAFE_IPO_RESERVE becomes effective at power on.
If the value in $MN_PROFISAFE_IPO_RESERVE exceeds the value set in
$MN_PROFISAFE_IPO_TIME_RATIO, then Alarm 27034 "Parameterization of
MD %1[%2] invalid" is output with the note relating to machine data
$MN_PROFISAFE_IPO_RESERVE.
Machine data bit $MN_SAFE_MODE_MASK, bit 3, to activate the modified
PROFIsafe driver sequence in the NCK, is incorporated in checksum
$MN_SAFE_GLOB_ACT_CHECKSUM[0]. Machine data
$MN_PROFISAFE_IPO_RESERVE is also incorporated in checksum
$MN_SAFE_GLOB_ACT_CHECKSUM[0].
7.2.6 parameterizing the SPL- - SGE interface
A bitwise assignment can be made using machine data to better link the SPL
interfaces to the net (useful) data of the F modules.
Symbolic name
In order to be able to display the various PROFIsafe modules in accordance with
symbols that can be specified by a machine manufacturer, using the MD fields
S $MN_PROFISAFE_IN/OUT_NAME[0...47]
it is possible to save symbolic names such as these. This name is used in the
following situations:
S Alarms: If a symbolic name for a PROFIsafe connection has been saved in the
MD mentioned, then this is displayed instead of the PROFIsafe address. This
applies to the following alarms:
27251 PROFIsafe: F module %1, %2 signals error %3
27254 PROFIsafe: F module %1, error on channel %2; %3<ALSI>%1 = name
27255 PROFIsafe: F module %1, general error
27257 PROFIsafe: %1 %2 signals system error %3 (%4)
S Diagnostic screens: In addition to the PROFIsafe address, the symbolic name
is also displayed in the diagnostic screens.
For PROFIsafe modules that are addressed in several MD blocks (several subslots
or several SPL couplings), then the symbolic name, which is saved in the MD set
with the lowest array index, is applicable. All other connection names are ignored.
The symbolic names can be freely selected and can be a maximum of 15 charac-
ters.
Machine data that contain symbolic names are not included in any checksum
calculation. The name can therefore be changed without aligning the checksum.
The value of the machine data becomes active after a control hot restart.
