it is possible to save symbolic names such as these. This name is used in the following

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%1 = name
27254 PROFIsafe: F-module %1, error on channel %2; %3<ALSI> %1 = name
27255 PROFIsafe: F-module %1, general error%1 = name
27257 PROFIsafe: %1 %2 signals system error %3 (%4)%2 = name - only if %1 = "F-
module"
● 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 characters.
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.
Note
The examples, now listed, to parameterize the SPL-SGE interface are based on the following
specifications:
F-DI module
- F-address: 114 = 90H
- F-net data length: 8 bytes
Machine data
MD10386 $MN_PROFISAFE_IN_ADDRESS[5] = 05 00 0090
MD13300 $MN_PROFISAFE_IN_FILTER[5] = 000F 000F
MD10388 $MN_PROFISAFE_IN_ASSIGN[5] = 008 001
MD13308 $MN_PROFISAFE_IN_NAME[5] = PS_IN_5
Assignment: PROFIsafe component to the F-master
F-net data of an F-DI module is sub-divided into units each 32 bits. Each of these 32-bit units
are known as sub-slots. This sub-division, for assigning the F-DI module to the F-master is
expressed in the sub-slot address.
