The maximum

data areas to be
transferred can
be found in the
device-specific
Part B of this
manual in the
"Performance
Data" chapter.
They may differ
for controller or
device mode.
S7-CPs for Industrial Ethernet Configuring and Commissioning
Remarks
Module base address
Specifies the address and length.
Controller mode:
The length should match the total length of
the distributed IO configured in HW Config,
whereby address gaps are also transmitted.
Device mode:
The data structure results from the order of
the slots of the input modules configured for
this PROFINET IO device on the PROFINET
IO controller line and their length without
address gaps.
(Please note the more extensive
explanations or examples for your CP in the
device-specific Part B of this manual)
Notes:
S
The block begins to transfer the data at
address 0 regardless of how you
configured the addresses (regardless of
the lowest configured address).
S
Specifying an I/O area is not permitted
since you must first change the IOCS for
GOOD before data can be accepted in
the I/O.
Length of the data area to be transferred in
bytes.
The transfer of the data always begins with
address 0 regardless of the configuration.
Please note that the IO address "0" with a
length of 1 is included.
Controller mode:
S
The highest configured address of the
devices must be specified here. The
individual areas are not grouped
together.
S
The data is transferred in the order of the
logical addresses (as with PROFIBUS
DP).
Device mode:
S
The data is transferred in the order of the
slots corresponding to the configuration
of the input modules on the PROFINET
IO controller line for this PROFINET IO
device.
S
Note
Make sure that the length programmed
here and the configuration of the
PROFINET IO controller are consistent.
