A data record of partial list ID W#16#xy91 has the following structure:
Name Length Meaning
Adr1 1 word For a central configuration: number of the rack
For a distributed configuration with PROFIBUS DP: DP
master system ID, station number
For a distributed configuration with PROFINET IO: bit 15
= 1 (PROFINET IO identifier) the last two places in the
PROFINET IO system ID, station number
Note: A PROFINET interface is always handled as an
"interface module in the central configuration", regardless
of the use for PROFINET IO.
Adr2 1 word For a central configuration and a distributed configuration
with PROFIBUS DP: slot number and interface module
slot number
For a distributed configuration with PROFINET IO: slot
number
Note: A PROFINET interface is always handled as an
"interface module in the central configuration", regardless
of the use for PROFINET IO.
Logadr 1 word First assigned logical I/O address (base address)
solltyp 1 word PROFINET IO: expected (configured ) type (see below)
otherwise reserved
isttyp 1 word PROFINET IO: actual type (see below) otherwise reserved
reserviert 1 word 00xx=CPU-Nr.1-4 (only S7-400)
for PROFINET IO:
SSL ID=W#16#0C91: number of actually existing
interface modules (without interface module 0)
SSL ID=W#16#0D91: number of interface modules
(without interface module 0)
SSL ID=W#16#4C91: number of actually existing
interface modules (without interface module 0)
SSL ID=W#16#4D91: number of actually existing interface
modules (without interface module 0)
eastat 1 word I/O status
Bit 0 = 1: module error
(detected by diagnostic interrupt)
Bit 1 = 1: module exists
Bit 2 = 1: module does not exist
Bit 3 = 1: module disabled
Bit 4 = 1: station error (only representative slot)
Bit 5 = 1: S7: A CiR event at this module /station is
busy or not yet completed
Bit 6 = 1: reserved for S7-400
Bit 7 = 1: module in local bus segment
Bit 8 to 15: data ID for logical address
(input: B#16#B4, output: B#16#B5,
external DP interface: B#16#FF)
