Note
The SINAUT ST7cc for WinCC expansion packet is described in detail in a separate manual.
To complete the "Introduction to the SINAUT ST7 system" in this chapter, we will
nevertheless briefly outline the properties of the SINAUT ST7cc package.
1.10.2 The special properties of SINAUT ST7cc
Telecontrol master with user-friendly diagnostics
● Direct connection of SINAUT ST7 TIMs to ST7cc over MPI and Ethernet. A separate CPU
as telecontrol master is not required.
● Availability of the most important status information of each SINAUT subscriber with
visualization in WinCC using provided station typicals (picture typicals and faceplates)
● Option of controlling SINAUT subscribers with these faceplates
● Identification of process values from subscriber stations with a disrupted connection to
ST7cc
● General request to affected stations following data transfer problems to allow the process
image to be updated in ST7cc
● For diagnostic purposes: Selective recording of message traffic for individual or all
SINAUT subscribers. Message visualization and evaluation is the same as with the TIM
message monitor.
● Time synchronization by ST7cc for the TIMs connected to the ST7cc PC over Ethernet
Preprocessing of process data
Preprocessing can be configured for binary, analog, and counted values. This takes into
account the event time and adds the time stamp of the event time to related messages and
archive entries.
● Binary values
– Entry of current binary values in the assigned WinCC tags
– Entry of related messages into the WinCC message system taking into account the
time stamp supplied by SINAUT
● Analog values (instantaneous and mean values)
– Floating-point numbers, integer values
– Linear raw value scaling (raw value --> physical value)
– Entry of analog values (with or without linear raw value scaling) in the assigned
WinCC tags
– Entry of analog values (with or without linear raw value scaling) into the WinCC
archive taking into account the time stamp supplied by SINAUT
