- 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
- Functional safety with WinAC RTX F for EC31-RTX F:
The functional safety is implemented by means of targeted safety functions in the software. Safety functions are implemented with S7 Distributed Safety, to place the plant in a safe state or to hold it in a safe state. The safety functions are mainly included in the following components:
- In the safety-related user program (safety program) in WinLC RTX F
- In the fail-safe inputs and outputs (F I/O).
The F I/O ensures reliable processing of the field information (emergency stop pushbutton, light barriers, motor 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 execute the actual user safety function, it will execute the fault response function: e.g. deactivation of the associated outputs and, if appropriate, F-CPU in STOP. - Retentivity:
The controller can back up 512 KB of retentive data on an integrated, non-volatile memory, without the need for a UPS. Total retentivity of all process values of SIMATIC WinAC RTX can be achieved with a generally available UPS. - Access to process values:
The SIMATIC NET OPC server supplied with EC31-RTX permits open access to all process values. Visualization systems or data processing systems can be linked to SIMATIC WinAC RTX via this interface. - Communication:
The Windows Automation Center (WinAC) is programmed with SIMATIC STEP 7 via the integral Industrial Ethernet interface. The SIMATIC NET SOFTNET Lean communication package is pre-installed for this purpose. - Use of other software:
The customer can install supporting software products. Windows Embedded Standard is designed so that typical add-on packages can be installed.
