Introduction In this example the fault output from an HS35iQ encoder was connected to a Rockwell PLC. A simple single line of ladder logic was used to read the fault line from the encoder and turn on an LED when a fault is present. The LED is just an easy way to indicate the fault was successfully read from the encoder but other solutions such as alerting maintenance are possible by utilizing the fault output function.
