This LED indicates the status of the PROFIBUS network when in Master mode
and the status of the configured field devices when in Slave Mode.
Master
Solid Red
– There are bus communication errors
Flashing Red
– There are field device errors
Off
– There are no bus communication or device errors
Slave
Solid Red
– There are bus communication errors (if no valid packet has been
received by any configured slave for more than 1s).
Flashing Red
– There are slave errors (at least one slave has not been
configured properly and is not exchanging DPV0 data).
Flashing Green
– All slaves are successfully exchanging DPV0 data and the
DP network operational state is
clear
.
Solid Green
– All slaves are successfully exchanging DPV0 data and the DP
network operational state is
operate

The activity LED is used for the activity on the Primary Interface (e.g.
EtherNet/IP, Modbus RTU, or Modbus TCP). Thus, every time a valid packet is
received from the Primary Interface the LED will toggle green. The LED will
toggle red if a corrupted packet was received (e.g. failed checksum when using
RS232 or RS485).
