Method for programming a safety-oriented programmable logic controller and router function block

A non-transitory computer readable medium containing a router function block for a safety-oriented programmable logic controller (SO-PLC), comprising:

• means for automatically converting second data provided by at least one first program part of the safety-oriented programmable logic controller (SO-PLC) into first data in order to activate a device-integrated safety function, wherein said device-integrated safety function is a drive-integrated safety function of a device connected to said safety-oriented programmable logic controller (SO-PLC), wherein said device-integrated safety function is activatable using predetermined first data, wherein the converted second data are also made available to at least one influencing device for comparing the second data with response data of the activated device-integrated safety function of the device, wherein said response data are made available to the influencing device in the form of first data, and the influencing device is forwarded output data in the form of second data back to the first program part, and wherein the non-transitory computer readable medium is configured to automatically interlock the second data,
• wherein said at least one influencing device includes a NOT gate, a first OR gate, a second OR gate, and a first AND gate and a second AND gate, wherein at least one second program part of the safety-oriented programmable logic controller (SO-PLC) is instantiated when the device is linked into a program of the safety-oriented programmable logic controller (SO-PLC), for converting the second data into the first data using the at least two influencing devices, wherein said first OR gate is configured to receive a value determined by said NOT gate and based on said value, forward said first data to an output channel and wherein said first AND gate is configured to receive inputs from said NOT gate and said second OR gate and forward first data to said second AND gate and to an output channel.
