PLCopen function blocks for the safety technology

(PresseBox) (Lemgo, ) KW-Software provides the PLCopen safety function blocks as certified library, called SAFEFB PLCopen. Within the context of PLCopen, a specification for standardizing safety-focused application software was worked out by the leading manufacturers of safety PLCs and external organizations (BGIA, TÜV Rheinland). The correct use of safe function blocks according to the PLCopen is simplified for the PLC programmer by the manufacturer-embracing functionality. The use of the PLCopen function blocks considerably simplifies the realization of the safety functions. No own blocks have to be created for the application. Due to the use of certified function blocks, the validation of the complete safety chain of the machine and plant respectively is considerably reduced. All blocks provide extensive diagnostic information of the connected protection unit. This makes it possible to inform the user about the status of the safety unit at any time. Further functions of the blocks are the interlocks according to PLCopen.

In addition to the PLCopen function blocks, SAFEFBTest gives the user the possibility to automatically verify his own function blocks. The technology package SAFEFBTest allows the user to generate an automated test case on basis of a status diagram. With only a few steps, test cases can be generated which automatically check afterwards the individual functions of the function block. Already at runtime of the automatic test, the test results are displayed on the SAFEFBTest user interface. After the test is completed, the user gets a complete test protocol. Due to the use of SAFEFBTest, the test effort for the user is reduced to a minimum with, at the same time, increased quality.
