ST7cc Config
ST7cc Config allows the parameter values required for message processing to be specified.
When the WinCC data framework is generated (in other words, message management), the
individual WinCC messages are generated and imported into WinCC.
ST7cc tag
An ST7cc tag is a data section from the data area of a SINAUT object that is managed and
processed as a separate information unit in the ST7cc server. The tags are processed,
however, in ST7cc and in WinCC. When the tags are defined, different processing can be
assigned to them depending on their type. A tag can contain both a process value as well as
status information from system components. System components are the SINAUT
subscribers.
ST7cc tag management
ST7cc tag management covers all ST7cc tags. The content of the ST7cc tags represents the
current process image. WinCC writes and reads the ST7cc tags.
ST7sc
The SINAUT system allows the networking of SIMATIC stations with a control center over a
WAN (Wide Area Network). This control center can also be a SIMATIC station or a PC-
based control center, for example, WinCC with the SINAUT ST7cc add-on.
SINAUT ST7sc allows the manufacturers of control systems to connect to SINAUT without
needing to integrate a SINAUT interface. Communication is over OPC: As an OPC server,
SINAUT ST7sc forms the interface between the SINAUT system and a control system
connected as an OPC client.
The OPC interface is also suitable for data exchange with other applications, for example,
the Microsoft Office application Excel.
Station
In the SINAUT world, the term station includes the entire hardware components required for
acquisition, processing and communication with other stations or a master station. A station
can, for example, consist of a modem, a TIM and a programmable controller (in turn
consisting of a CPU and I/O modules). A SINAUT station can also include several
programmable controllers, or, in the case of a node station, several TIMs.
Station TIM
WAN interface of a TIM set to the "station" function. Use in stations.
Status message
A status message is a process status (for example pump on, valve open) or alarm (for
example limit value exceeded). This is binary information with the possible values 0 or 1.
Eight status messages are put together to form one byte.
