System interfaces for SIMATIC HMI
System interfaces with WinCC
SIMATIC WinCC
Mixed operation with different controls
With their multi-protocol stack, the CP 1613 and CP 5613 com-
munication processors allow parallel operation of two protocols,
such as for the mixed operation of different controls, via a bus
cable. WinCC supports the operation of two similar interface
boards only in connection with the channels SIMATIC S5
Ethernet Layer 4 (2 x CP 1613), SIMATIC S7 Protocol Suite
(2 x CP 1613, 2 x CP 5613) as well as PROFIBUS DP
(4 x CP 5613; each CP 5613 max. 122 slaves). In addition to
communication over industrial Ethernet CP 1613 or PROFIBUS
CP 5613, one CP 5611 can be used in each case for communi-
cation with SIMATIC S7 via MPI.
Client-server communication
Communication between the clients and the server is via TCP/IP
protocol. Setting up a separate PC LAN is recommended. For
small projects with a correspondingly low incidence of message
frames, SIMATIC NET Industrial Ethernet communication can be
used for both process communication (WinCC/Server
PLC)
and PC-PC communication (WinCC/client
WinCC/server).
Channel DLL PROFIBUS DP
In accordance with the PROFIBUS standard, DP/slaves are al-
ways permanently assigned to a DP master; i.e. a second
WinCC station (DP/master) cannot access the same controls
(DP/slave). This means that redundant operation of two WinCC
stations is not possible using the PROFIBUS DP connection.
Connection to controls from other manufacturers:
OPC (OLE for Process Control) is recommended for the connec-
tion of controls from other manufacturers.
Current notes and information about OPC servers from various
suppliers can be found at:
WinCC supports the standards:
•
OPC Data Access 2.05a
•
OPC Data Access 3.00
•
OPC XML Data Access 1.00 (Connectivity Pack/Connectivity
Station)
•
OPC HDA 1.20 (Connectivity Pack/Connectivity Station)
•
OPC A&E 1.10 (Connectivity Pack/Connectivity Station)
•
OPC UA Client Data Access
•
OPC UA Server Data Access, HDA (Connectivity Pack /
Connectivity Station)
Connection overview
1)
WinCC version V7.2 or higher supports communication
with S7-1200 / S7-1500 CPU.
Restrictions:
No symbolic address, type safe structure support (absolute address only)
No CPU alarming support
2)
Application note:
Parallel usage of the OPC client channel allows, for example, connection
to an SNMP-OPC server for visualization of the data contained there. The
SNMP OPC server enables monitoring of any network components (such
as switches) that support the SNMP protocol. You can find more infor-
mation under SIMATIC NET Communications Systems/SNMP OPC Server.
3)
WinCC V7.0 SP3 and later supports OPC UA (United Architecture) Client
for DA.
