Automation safety software
LASAL SAFETY SIGMATEK

The full integration of the SAFETY Designer into the LASAL engineering toolkit simplifies the programming and configuration of the Safety controller. Logic operations and I/O configurations can be created comfortably.

With the function library, which in addition to standard function blocks, provides Safety function blocks based on the PLCopen standard such as Emergency Stop, Two Hand Control or Guard Locking, the user can easily create the logic operations for the Safety related procedures. In the integrated graphic editor, function blocks and I/Os can be easily placed through Drag & Drop and connected to the non-safe variables of the PLC. Downloading, online monitoring and debugging are done over LASAL's online interface. Several Safety controllers can be used per project, whereby the program in each Safety controller can be distributed over any number of networks. The simple operation and clearly organized representation reduce the time and effort for programming, maintenance, diagnosis and especially for the validation.

For communication, no additional wiring is needed. Standard data as well as Safety-relevant data can be exchanged over the Ethernet based, hard real-time capable VARAN bus. For communication between the Safety components, the "Black-Channel" principle is used, in which the bus does not assume any Safety-relevant tasks but serves as a single-channel data exchange medium only and does not have to be included in Safety considerations.
