Which communication LEDs must be implemented (are mandatory) to achieve certification
PROFINET
Signal LED must be available on case. A red blinking LED must blink 3 time in 3 seconds = 1 Hz if signaling is forced over DCP.
EthernetIP
EtherCAT:
For EtherCAT take the document ETG700. EtherCAT has strong rulse for printing lables on the case and LED.
Use the lable "RUN" or "RN" and Green LED. On NXHX90 this is the COM0 LED; Lable need to be close to the RUN LED
Use the lable "ERR" or "ERROR" or "ER" and Red LED. On NXHX90 this is the COM1 LED; Lable need to be close to the ERR LED
Use the lable "IN" for Port 0 together with Lable "LINK/ACTIVITY" or "LINK/ACT" or "L/A" or "LA" and Green LED. (Yellow LED is not used for EtherCAT) The lable need to be close to Port0 or obviously allocated to Port0
Use the lable "OUT" for Port 1 together with Lable "LINK/ACTIVITY" or "LINK/ACT" or "L/A" or "LA" and Green LED (Yellow LED is not used for EtherCAT) The lable need to be close to Port1 or obviously allocated to Port1
