Mode Status Meaning
Flashes – Flashes briefly whenever a valid message is received by the
Fieldgate on the RS-485 communication line.
– The LED does not flash if the message is not addressed to the
Fieldgate or if a communication error was detected within the
message.
Off – Currently no communication on the RS-485 line.
Mode Status Meaning
On OK Fieldgate SWG70 is powered up and running
Flashes Not ready On power-up, indicates that the Fieldgate application is running
but the Fieldgate is not yet ready to answer HART commands.
Off No power The power supply is not connected/Fieldgate is not ready.
Mode Status Meaning
Flashes – Flashes shortly whenever a valid WirelessHART message is
received by the Fieldgate on the WirelessHART communication
interface.
– Messages include simple commands but not published bursts
and event notifications.
Off – Currently no communication on the WirelessHART interface.
Mode Status Meaning
On Hardware fault Fieldgate has detected a hardware fault that makes normal
operation impossible.
Flashes Recovering from hardware
fault.
The Fieldgate application is trying to recover from the fault (not
possible for all faults).
Off No hardware fault –
