o
Unsolicited Max Retries
If initial unsolicited response is not confirmed, the unit will continue to retry the
transmission, at the rate defined by the confirm timeout and retry delay, until the
number of retries specified by this parameter have been made.
The unit then concludes that the server must be offline, and switches to “offline”
mode.
o
Unsolicited Offline Delay
Additional time, in seconds, after an unsolicited response confirmation has timed
out, to delay before resending an unsolicited response in “offline” mode.
That is, after “max retries” attempts to resend an unsolicited response, the unit will
continue to re-send unsolicited responses as before, but now the period between
retries equals the confirm timeout plus this offline retry delay.
To disable retries in offline mode, enter an offline delay > 86400 seconds (= 1 day).
This will be converted to 2678400, which is interpreted as an infinite delay. The total
number of retries will then equal the “max retries” parameter.
Or, to specify an infinite number of retries at the same rate, set the offline delay
equal to the retry delay (max retries is not relevant in that case).
By default, these parameters are calculated internally, based on how the unit connects (LAN
or modem) and, for modem connections, the event reporting period. This is indicated by
“default” appearing as the value.
If you enter your own value for any of these parameters, that value will be used instead of
the default calculation, regardless of connection mode.
Note:
unless you have specific requirements, you should not need to set any of these
parameters.
