■
Overview
System configuration SOFTNET for Industrial Ethernet
•
Software for coupling programming devices/workstations
to automation systems
•
Communication services:
- PG/OP communication
- S7 communication
- Open communication (SEND/RECEIVE)
•
Can be used with
- Layer 2 Ethernet card (PCI/PCIe), e.g. CP 1612 A2
- Integrated Industrial Ethernet interface
- Modem/ISDN (Remote Access Service RAS)
•
Complete protocol stack as a software package
•
Increased availability thanks to additional option packages
such as OPC Server Redundancy
■
Benefits
•
Maximum transparency due to integrated communication with
SIMATIC via Industrial Ethernet and OPC as the standard
interface
•
Low-cost solution for industrial use in PCs that require smaller
quantity structures
•
Simple and low-cost commissioning thanks to uniform
procedure and configuration functionality with NCM PC and
STEP 7
•
Increased availability of the plant information by means of
redundant SIMATIC NET OPC server
■
Application
With SOFTNET for Industrial Ethernet, PC/PG and workstations
can be connected to programmable controllers, such as
SIMATIC S7, over Industrial Ethernet.
The following user interfaces are available:
•
PG/OP communication for SIMATIC S7
•
Open communication (SEND/RECEIVE) for communication
with SIMATIC S5 and S7
•
S7 communication
SOFTNET is available for the following interfaces:
•
Layer 2 Ethernet card (PCI/PCIe), e.g. CP 1612 A2
•
integrated Industrial Ethernet interface
•
Modem/ISDN (Remote Access Service RAS)
■
Function
With SOFTNET, the complete protocol stack is processed
in the PC.
This architecture means that in contrast to the CP 1613 A2/
CP 1623/CP 1628 communications processors, the perfor-
mance of the SOFTNET packages is dependent on the configu-
ration or capacity utilization of the PC used.
The IT functionality is established in connection with the inter-
faces and the PC's Windows software.
User interfaces
OPC interface
The OPC server included in the respective software package
can be used as the standard programming interface for the
S7 communication and open communication protocols in
order to connect automation technology applications to OPC-
compatible Windows applications such as Office, HMI systems,
etc.
Software for PG/OP communication
This software makes it possible to program the S7 controllers via
Industrial Ethernet in conjunction with the STEP 7 engineering
software.
Software for S7 communication
SIMATIC S7 system components communicate with each other
using S7 communication functions.
The S7 communication can be based optionally on the
ISO protocol or the TCP/IP protocol.
S7 communication offers the following services:
•
Administrative services
•
S7 connection management services
•
Variable services
•
VFD (Virtual Field Device) services
•
Trace and mini database
