SINAUT ST7cc, Add-on for WinCC

■
Design
SINAUT ST7cc is installed on a Windows PC. WinCC can also
run on the same PC. However, client/server configurations are
also possible, in which the ST7cc is located on the WinCC
server.
The following software packages and licenses are required for
an ST7cc control center that is configured as a single-channel or
redundant system with WinCC. A license for the WinCC com-
plete package is required. A runtime package may be sufficient
if no configurations are required on the end computer. The
WinCC redundancy package incl. license is also required for the
redundant ST7cc.
The table below lists the software packages required for the
ST7cc non-redundant/redundant system in detail.
1)
A runtime package may be sufficient if no configurations are required
on the end computer.
One or several SINAUT ST7 TIM communications processors
are connected to the ST7cc PC depending on the TIM type used
either via the MPI bus or via Ethernet. Both ST7 and ST1
terminals can be connected to the TIMs, only ST7 terminals to
the TIMs on the Ethernet.
Provision of current time of day:
•
Time synchronization for TIMs connected via MPI to the ST7cc
PC is only possible using a TIM equipped with a DCF77
receiver. This is then responsible for central synchronization of
the ST7cc PC and all terminals.
•
Time synchronization for TIMs connected via Ethernet to the
ST7cc PC is via ST7cc.
Outside the reception area of the DCF77 real-time transmitter
the use of a GPS receiver is recommended. This determines the
local time from the satellite-based global positioning system
(GPS).
■
Function
Functioning as a remote control center
with convenient diagnostic functions
•
Direct connection of SINAUT ST7 TIMs over MPI and Ethernet
to ST7cc. A separate series-connected S7-300 or S7-400
controller is not required as a central remote control center.
•
Provision of the most important status information for each
SINAUT ST7 or ST1 station with visualization in WinCC using
supplied station typicals (display typicals and faceplates).
•
Control possibilities for the SINAUT stations over these
faceplates.
•
Tagging the process values from stations with an interrupted
connection to ST7cc.
•
General scanning of affected stations following the end of a
transmission fault for updating the process image in ST7cc.
•
For diagnostic purposes: Selective activation of recording
of the message traffic for individual or all SINAUT stations.
Message frame visualization and evaluation is performed in
the same manner as by the TIM message frame monitor.
•
Time synchronization by ST7cc for the TIMs that are
connected to the ST7cc PC over Ethernet.
Preprocessing of process data
Preprocessing can be configured for binary values, analog
values, and count values. They take into account the event time
points and tag derived alarms and archive entries with correct
time stamps.
•
Binary values
- Entry of current binary values into the assigned WinCC tags
taking into account the time stamps supplied by SINAUT ST7
or ST1.
•
Analog values
(current and average values)
- Floating-point numbers, integer values
- Linear raw value conversion (raw value
physical value)
- Entry of analog values (with or without linear raw value
adaptation) in the associated WinCC tags
- Entry of analog values (with or without linear raw value
adaptation) into the WinCC archive taking into account the
time stamps supplied by SINAUT ST7 or ST1.
•
Count values
- Overflow handling in the case of absolute counters.
- Count value conversion using factors
- Generation of correct interval times
- Entry of currently accumulating interval quantities in the
assigned WinCC tags.
- Entry of complete interval quantities into the WinCC archive
taking into account the time stamps supplied by SINAUT ST7
or ST1.
•
Setpoints
- Floating-point numbers, integer values
- Linear raw value conversion (physical value
raw value)
if required.
Simple, integrated configuring
Configuration of the overall system with ST7ccConfig is very user
friendly. A separate WinCC configuration for tag management,
archive and alarm system is limited to a few preparatory
measures, such as the creation of archives and, in the case of
WinCC, the definition of alarm classes and types.
