S7-CPs for Industrial Ethernet Configuring and Commissioning
Release 01/2007
C79000-G8976-C182-07
In some situations, it is an advantage to set up communication connections not
over the configuration interface of STEP 7 but program-controlled by specific
applications.
As of STEP 7 V5.2 SP1, a function block is available for these applications that
allows flexible transfer of data blocks with configuration data to an Ethernet CP.
The description of the configuration for FETCH / WRITE services has been
extended.
New in release 06 / STEP7 V5.2 (C79000 -G8976 -C129 -06)
S7 communication over routers (single-ended client and server functionality) via
an IE/PB Link or CP.
Multiprojects
With the new multiproject functionality, projects can be split up and distributed
for engineering and then merged again.
New in release 05 / STEP7 V5.1 SP3 (C79000 -G8976 -C129 -05)
Configuring multicast and broadcast on UDP connections.
See Chapter 5.
The blocks AG_SEND and AG_RECV can now be used for “long data packets”
with an S7-300. See Chapter 7.
The S7 CPs for Ind. Ethernet are now supplied with a default MAC address
allowing configuration data to be downloaded over Ethernet without a ”node
initialization”.
