8.23.4.2 Outline of the Safety Logic Circuit Expansion Function
In the safety logic circuit expansion function, input and output signals and
logic (instructions) available in the logic circuit are expanded. Also, the
signal that has been attained by the hardware can be also attained by the
safety PLC (optional function). The machine safety board monitors the
hard-wired signal at all times. Therefore the safety function to turn OFF
the servo power supply to the manipulator when an error is detected is still
maintained.
Also, by using MS-OUT signal (the output data from the machine safety
board) and FS-OUT signal (the output data from the functional safety
board), the data can be transferred between the machine safety board
and the functional safety board (optional).
The following is the signal flow in the safety logic circuit expansion
function.
