WCS read head: LED status indicator and rotary coding switch
Power/State:
The "Power/State" LED lights up green: voltage supply is present.
State:
The "State" LED is green: Data is being exchanged with the WCS read heads. The four
"ErrorNo/Select ID" LEDs are used to display the number of the currently polled read head.
The "State" LED lights up red: The interface module has detected an error or a warning. The
interface module uses the "ErrorNo/Select ID" LEDs to display the binary coded error number
or warning number, and sends the number to the PROFIBUS master via the external diagnostic
byte.
