PROFINET/Industrial Ethernet
System interfaces for PG/PC/IPC
Communication for PC-based systems
Introduction
2
■
Overview
CPs with an internal microprocessor
•
Protocol software executes on the CP
•
Free PC resources for applications
•
Suitable for comprehensive applications
•
Recommended for applications with HMI systems which have
high performance requirements, e.g. WinCC
•
Recommended for large systems
(eight stations or more, e.g. SIMATIC)
•
Constant communication throughput
•
Can be used for redundant communication
•
Use for PROFINET IO real-time applications
(RT, IRT with CP 1616/CP 1604)
•
Time synchronization
CPs without internal microprocessor
•
Protocol software executes on the PG/PC
•
PC resources are divided between communications and
applications
•
Suitable for less comprehensive applications
•
Recommended for smaller applications (up to eight stations,
e.g. SIMATIC)
•
Communications performance depends on PC resources and
PC loading
CPs with integral switch
•
Connection of additional field devices to the Industrial
Ethernet by means of additional switch ports
•
Switch operation possible via external power supply even with
PC turned off
Configuration for SIMATIC NET version V12 or higher
STEP 7 V12 or higher is used for PC configuration. The STEP 7
software is included in the scope of delivery of the SIMATIC NET
products. A STEP 7 license is not required for PC configuration.
Configuration for SIMATIC NET versions up to V8.2:
The PC can be configured either in STEP
7 or in NCM
PC Version
V5.1+SP2 and higher. Both tools offer the same 'look & feel' and
create the same database. This enables integrated configura-
tion of the open communication and S7 communication func-
tions. Data only has to be entered once and data consistency is
assured.
•
A configuration wizard integrated into NCM PC also supports
user-driven configuration of the PC station.
•
With NCM PC and STEP 7 from Version V5.1+SP2 upwards, a
PC similar to a SIMATIC S7 station can be configured and
loaded over a network. This applies both to the local station on
which NCM PC or STEP 7 is installed and to the remote station
that is addressed over the network.
Note:
NCM PC does not contain a conversion function for LDBs that
were created using COML S7. Reconfiguration is necessary.
You will find software products on
the SIMATIC NET/Windows CD.
Development Kits are available for
use in various operating system
environments
(e.g. for CP 1616 or CP 1604).
As a rule, the necessary
configuration tools are included in
the software packages.
Manuals in PDF format and
extensive supplementary
information on SIMATIC NET
products and communication can be
found in the SIMATIC NET Manual
Collection which is enclosed with
the software products.
