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.
