Note
Examples of the PLC blocks can be requested from the Centre of
Competence Service (CoCS) – Sinumerik Safety Integrated.
Also refer to Chapter 2.10.
The PLC blocks, listed in Chapter 7 are available as example in the toolbox for
the basic PLC program. Further, an S7 library can be requested via Customer
Support (refer to 2.10) within the scope of a Hotline request. This S7 library has
example blocks for the SI application that can be generally used. They can be
incorporated in a specific project and adapted to the particular requirements by
appropriately parameterizing them.
In this example, PLC blocks FC95 (start ASUB), FC96 (PLC-SPL), FC97
(safety test routine) are used for Safety Integrated.
The basic program blocks FB4 and FC9 are called (FB1/P3) in FC 95 to start
the NCK ASUB. The parameter supply for FC9 and FB4 is stored in DB120.
