2.12.8 FB 10: Safety relay (SI relay)
Description of functions
The SPL block "Safety relay" for "Safety Integrated" is the PLC equivalent of the NC function
of the same name. The standard SPL "Safety relay" block is designed to support the
implementation of an emergency stop function with safe programmable logic. However, it
can also be used to implement other similar safety functions, e.g., control of a protective
door.
