S7-CPs for Industrial Ethernet Configuring and Commissioning
Release 01/2007
C79000-G8976-C182-07
Functions (FCs)
STEP 7 code blocks of the type ”function”.
Gateway
Intelligent connectivity device that connects local area-> networks of different
types at the ISO Layer 7 level.
Industrial Ethernet
A LAN system complying with IEEE 802.3 (ISO 8802-2)
Multicast
A multicast is like ”calling all group stations”: Using one multicast frame, you can
reach all the nodes that belong to the multicast group and that are prepared to
receive frames.
NCM S7 for Industrial Ethernet
Configuration software for configuration and diagnostic functions on an Ethernet
CP.
NCM S7 for PROFIBUS
Configuration software for configuration and diagnostic functions on a
PROFIBUS CP.
Network
A network consists of one or more interconnected -> subnets with any number
of -> nodes. Several networks can exist side by side.
PC station
PC station means a PC with communications modules and applications. This PC
is intended, for example, to communicate with SIMATIC S7 devices during
process control tasks. These PCs equipped with runtime software are also
known as runtime stations.
The PC station is configured in SIMATIC NCM PC / STEP 7 for communication
with SIMATIC S7 devices.
The required runtime software is available on the PC station after APC
(Advanced PC Configuration) is installed.
PG operation
A mode of the PROFIBUS/Ethernet CP in which the SIMATIC S7-CPU is
programmed, configured or diagnosed over PROFIBUS/Ethernet. This mode is
handled by the S7 functions.
