Use of safe standard function blocks

Currently, the PLCopen workgroup has specified 20 safe function blocks regarding their inputs/outputs, state engine, error recognition and error handling. These blocks include important safety functions such as Emergency Stop, Safety Door, Mode Selector and Two-Hand Control.

Advantages by standard FBs

The correct use of safe function blocks according to the PLCopen is simplified for the PLC programmer by the manufacturer-embracing functionality. This also includes the low need for training and the easier transferring of programmed safety functions to different PLC systems. A further advantage is the low effort arising for the commissioning staff when validating the PLC program, as parts of the safety logic are based on already certified software modules.
