TwinCAT
KL1501, KL1512
42
Version: 3.1.0
Start/stop behavior
Depending on the setting, TwinCAT is started and stopped manually or automatically. Since TwinCAT is
integrated into Windows NT/2000/XP as a service, an operator is not needed to start the system: switching
on is enough.
Restarting and data backup
When a program is started or restarted, TwinCAT loads programs and remanent data. To backup data, and
to shut down Windows NT/2000/XP correctly, a UPS (uninterruptible power supply) is of great value.
TwinCAT and "Blue Screen"
The TwinCAT system can be configured such that real-time capability is maintained in the event of a BSOD
(Blue-Screen-of-Death) operating system crash. Real-time tasks such as PLC and NC can thus continue to
run and place the controlled process in a safe state. Ultimately, it is the decision of the programmer whether
or not to utilize this feature, bearing in mind that data or programs may already have been destroyed by the
BSOD.
World-wide connection through message routing - "remote" connection is inherent to the system
According to the requirement for operating resources, the TwinCAT software devices can be distributed:
TwinCAT PLC programs can be executed on PCs and on Beckhoff Bus Terminal controllers. A "message
router" manages and distributes all the messages, both in the system and via TCP/IP connections. PC
systems can be connected to one another by TCP/IP; Bus Terminal controllers are connected via serial
interfaces and fieldbus systems (EtherCAT, Lightbus, PROFIBUS DP, PROFINET, Interbus, CANopen,
DeviceNet, RS232, RS485, Ethernet TCP/IP, Ethernet/IP).
World-wide access
Since standard TCP/IP services from Windows NT/2000/XP are used, this data exchange can take place
worldwide. The system offers scalable communication capacity and timeout periods for the monitoring of
communications. OPC provides a standardized means for accessing many different SCADA packets. The
SOAP (Simple Object Access Protocol) enables a connection between two computers to be established by
means of an internet connection via standard HTTP. A TwinCAT component is available for this purpose.
