3.2.10.3System status lists (SSLs) in PROFINET IO

Chapter Content

This chapter explains the following:

•Which SSLs are intended for PROFINET

•Which SSLs are intended for PROFIBUS DP

•Which SSLs are intended for both PROFINET IO and PROFIBUS DP

Compatibility of the new SSLs

For PROFINET IO, it was necessary to create some new SSLs, among other things, because larger configurations are now possible with PROFINET.

You can also use these new SSLs with PROFIBUS.

You can continue to use a known PROFIBUS SSL that is also supported by PROFINET. If you use an SSL in PROFINET that does not support PROFINET, an error code is returned in RET_VAL (8083: Index wrong or not permitted).

Comparison of the System Status Lists of PROFINET and PROFIBUS

Table 3-9	Comparison of the System Status Lists of PROFINET and PROFIBUS
SSL-ID		PROFINET IO	PROFIBUS DP	Applicability
W#16#0591		yes	Yes	Module status information for the interfaces of a
		(parameter adr1 changed)		module/submodule
W#16#0A91		yes	Yes	Status information of all subsystems and master
		(parameter adr1 changed)		systems (S7-300 without CPU 318-2 DP)
W#16#0C91		yes	Yes	Module status information of a module/submodule in a
		(parameter adr1/adr2 and		central configuration or attached to an integrated DP or
		expected/actual type ID		PN interface module using the logical address of the
		changed)		module.
W#16#4C91		yes	Yes	Not with S7-300
		(parameter adr1 changed)		Module status information of a module/submodule
				attached to an external DP or PN interface module
				using the start address
W#16#0D91		yes	Yes	Module status information of all modules in the
		(parameter adr1 changed)		specified rack/station
new:		Yes	Yes	Module status information of all submodules of a
W#16#0696				module using the logical address of the module, not
				possible for submodule 0
new:		Yes	Yes	Module status information of a submodule using the
W#16#0C96				logical address of this submodule
W#16#xy92		No	Yes	Rack/stations status information
		(replacement: SSL-ID		Replace this SSL with the SSL with the ID W#16#xy94
		W#16#0x94)		in PROFIBUS DP as well.
new:		Yes	Yes	Rack/station status information
W#16#0x94
