Function
User interfaces
OPC interface
The OPC server included in the respective software package
can be used as the standard programming interface for the pro-
tocols S7 communication and open communication, in order to
connect automation technology applications to OPC-compatible
Windows applications (Office, HMI systems, etc.)
Programming interface through C library
The programming interfaces for the S7 communication, PG/OP
communication, and open communication protocols for existing
applications are implemented as Dynamic Link Library (DLL)
interfaces.
The released compilers can be found in the readme file
of the SIMATIC NET CD products at
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.
It is contained in all CP 1628 software packages.
Software for S7 communication
(HARDNET-IE S7 or HARDNET-IE S7-REDCONNECT)
The S7 interface allows PG/PC applications (e.g. WinCC) and
user programs to access the SIMATIC S7 system components.
This provides easy, flexible access to the data of the SIMATIC S7
controller.
S7 communication offers:
Administrative services
•
Connection management
•
Mini database
• Trace
Data transfer services
•
Read/write variables
• BSEND/BRECEIVE
H-communication
For redundant S7 communication with a fault-tolerant S7-400H
system, the CP 1613/CP1623/CP 1628 can be used in connec-
tion with the HARDNET-IE S7-REDCONNECT software.
Software for open communication (SEND/RECEIVE)
This interface is used for communication between
•
PG/PC and SIMATIC S5
•
PG/PC and SIMATIC S7
•
PG/PC and PG/PC
Open communication (SEND/RECEIVE) offers the following
services:
•
Management services
•
Connection establishment services
•
Data transfer services
These functionalities are a component part of the
HARDNET-IE S7 software product.
Security mechanisms:
Integrated security mechanisms enable safeguarding of
important computer systems, including their associated data
communication systems:
•
Stateful Inspection Firewall for filtering connections on the
basis of their IP/port addresses
•
Bandwidth limitation to avoid communication overload
•
Secure and encrypted access to controllers or remote access
over the Internet by means of VPN Server and VPN Client and
checking of data integrity
•
Tap-proof transmission of network analysis information to the
network management system (SNMP V3)
•
Secure transfer of the time of day (NTP V3)
•
Traceability by means of data logging on the basis of standard
IT mechanisms (Syslog)
Mode of operation
Protocols up to Level 4 (Transport) are processed autonomously
on the module.
The internal memory is available for this purpose and it also
provides for a large quantity structure and high communication
reliability.
Data is exchanged between the module and the host in master
mode. This means that the CP 1628 accesses the physical RAM
of the host.
A Windows driver transfers the data between the host system
and the CP 1628. The transmission rate to Industrial Ethernet is
detected and automatically switched over (autosensing).
The IT functionality is provided in combination with the Windows
software of the PC.
Diagnostics
All MIB-2 objects, for example, can be read out via SNMP.
This enables the current status of the Ethernet interfaces to be
retrieved.
Configuration
•
The S7 communication and open communication protocols
are configured in STEP 7 or NCM PC.
•
A configuration tool is included in the scope of delivery of the
CP 1628 software packages.
