Visualization

• SIMATIC WinCC RT Advanced can be ordered as a pre-installed, ready-to-use option. WinCC RT Advanced offers powerful functions for visualizing the processes at the machine.
• A retentive message buffer is available on an additional partition.

Control

For the optimum control of processes with WinAC RTX, several processing levels are available:

• Cyclic program processing
• Interrupt processing
• Time and date-controlled processing
• The controller can save up to 128 KB of retentive data on an optional, non-volatile memory without the need for an uninterruptible power supply (UPS)
• Total retentivity of all process values of SIMATIC WinAC RTX can be achieved with a generally available UPS

Functional safety with WinAC RTX F

• The functional safety is implemented by means of targeted safety functions in the software. Safety functions are implemented with the S7 Distributed Safety system, to place the plant in a safe state or to hold it in a safe state. The safety functions are mainly contained within the following components:
  
  • In the safety-related user program (safety program) in WinLC RTX F
  • In the fail-safe inputs and outputs (fail-safe I/O)
• The fail-safe I/O ensures safety-related processing of the field information (emergency stop pushbutton, light barriers, motor pre-control). It features all the hardware and software components required for reliable processing, according to the required safety class. The user only programs the user safety functions. The safety functions for the process can be implemented with a user safety function or a system-internal fault reaction function. If the F system is unable to perform the actual user safety function in the event of a fault, it performs instead the fault response function, e.g. the associated outputs are switched off and the F-CPU enters the STOP state.

Open access to process values

• The SIMATIC NET OPC server (versions with WinAC RTX) supplied with the SIMATIC IPC277D bundles provides open access to all process values. Any visualization systems or data processing systems can be linked to SIMATIC WinAC RTX via this interface.

Communication

• Programming of WinAC RTX with SIMATIC STEP 7 and transfer of the WinCC RT Advanced project is performed via the integral Industrial Ethernet interface. The communication package SIMATIC NET SOFTNET S7 Lean is installed for this purpose.

Using other software

• The customer can install supporting software products. Windows Embedded Standard is designed so that typical add-on packages can be installed.
