Compatibility of the New System Status Lists
For PROFINET IO, the system status lists had to be revamped to some extent because,
among other things, larger configurations are now possible with PROFINET.
You should also use these new system status lists with PROFIBUS.
You can continue to use a known PROFIBUS system status list that is also supported by
PROFINET. If you use a system status list in PROFINET that PROFINET does not support,
an error code is returned in RET_VAL (8083: Index wrong or not permitted).

SSL-ID PROFINET IO PROFIBUS DP Applicability
W#16#0591 yes
(parameter adr1 changed)
Yes Module status information for the interfaces of a
module
W#16#0A91 Yes
(parameter adr1 changed)
Yes Status information of all subsystems and master
systems (S7-300 without CPU 318-2 DP)
W#16#0C91 Yes
(parameter adr1/adr2 and
set/actual type identifier
changed)
Yes Module status information of a module in a central
configuration or attached to an integrated DP or PN
interface module using the logical address of the
module.
W#16#4C91 Yes
(parameter adr1 changed)
Yes Not with S7-300
Module status information of a module attached to an
external DP or PN interface module using the start
address
W#16#0D91 Yes
(parameter adr1 changed)
Yes Module status information of all modules in the
specified rack/station
W#16#0696 Yes No Module status information of all submodules of a
module using the logical address of the module, not
possible for submodule 0 (= module)
W#16#0C96 Yes Yes Module status information of a submodule using the
logical address of this submodule
W#16#xy92 No
(replacement: SSL-ID
W#16#0x94)
Yes Rack/stations status information
Replace this system status list with the system status
list with ID W#16#xy94 in PROFIBUS DP, as well.
