Communications
failure
For inputs, this bit is set (“on”) if no message has been received from
the remote address within the timeout period configured for this input.
The bit is reset ("off") when a message is received.
For outputs, this bit is set (“on”) if transmission to the remote was
unsuccessful after five attempts. The bit is reset ("off") when a
message is transmitted successfully. This bit may also be set if the
Disable Output Transmissions on Comms Fail option is selected - see
the Radio Comms Failure section.

Start-up status
For inputs, this bit remains set ("on") following start-up until a
message has been received for this input to give an initial input value.
For outputs, this bit remains set ("on") following start-up until the WI-
GTWY-9-xxx sends the first radio message for this output to the
remote address.

Timer
For inputs, the timer value is set to the configured comms fail time for
the input whenever a message has been received for this input. The
timer value will decrease until another message is received. When the
timer value reaches zero, the comms fail status is set. If the configured
comms fail time is zero, then the comms fail status for this input is
never set.
For outputs, the timer value is set to the configured update time for the
output whenever a message is transmitted by the GTWY-9-xxx to the
remote address. The timer value decreases. When the timer value
reaches zero, another update message is transmitted to the remote
address. If the configured update time is zero, no update messages are
transmitted for this output.
