To guarantee compatibility, a time-base clock is integrated into the mainboard or the peripheral computer interface. The time-base clock fails to start when special conditions occur. If hardware and software do not offer the correct basis, the time of day can be directly input via the PC's keyboard via the DAI (Digital Absolute In) input interface. Beckhoff combines itself a digital inverter and the respective decoder IC, thereby effecting the requested signal conversion from the input interface (DAI) to the output interface (DAO).
TwinCAT supports the standard programming interface for safety-critical systems (SMPLC) and the monitor tool PCSIA, with the Beckhoff 'v2' specification. TwinCAT runs independently in the event of failure and displays the system load. The user-defined threshold for the system load determines the time when a system message is triggered.
The SMPLC (Safety Multiprocessing Ltd) EK0100 SMPLC-PCI interface, which is especially developed for Beckhoff IO, realizes safety-critical processing in the space of a safety-critical device. This optical interface has a resolution of 6 bit. It is suitable for safety-critical devices in the field of industrial automation, machine control and process control. This interface is implemented as a PCI card.
TwinCAT 3 is used in the areas of engineering and manufacturing. For these fields of application, optimization of networking and interface capabilities are particularly important. TwinCAT supports the IEC 61850 standard (Data Communications, Process Instrumentation, and Control Networks) at the level of its SMPLC interface and at the level of its features, which are identified by the SMPLC-PCI interface. In addition, TwinCAT can support the EtherNet/IP standard for optimization of network interfaces. d2c66b5586
