Watchdog failure actions
When the N-111 fails to receive a number of consecutive pings from the target
device, it will trigger the AUX contact output for a time period determined by the Aux
Time setting. This output is intended to be used to trigger an alarm buzzer or light, or to
cycle power on a small DC-powered device. The contact is rated for 42 volts, up to 1
Amp current, and should not be used to switch line voltage or any device which draws
more than 1 Amp.
The N-111 can also optionally send a TCP message of up to 40 characters to a
target address on the network. IP:PORT indicates the network IP address and port of
the target device. This may be up to 24 characters long and must consist of an IP
address in dotted-quad format, followed by a colon, followed by a port number in the
range of 0 to 32767. The default setting of “0.0.0.0
:23
” indicates no action to be taken.
The TCP Message field holds a text message of up to 40 characters. When a
ping response occurs, this message will be sent to the specified network address.
The Email Message field holds a text message up to 80 characters long which
will be sent to the email address specified in the IP Ethernet Setup screen. If a message
is specified here, it will be sent to this address when a watchdog failure occurs.
The Test Restart button is used to manually trigger a Watchdog reset. This will
trigger the aux output to occur, and if specified will trigger a TCP message to be sent
and an Email notification to be sent.
Setting Default Value Range
Aux time 15 seconds 1-9999 seconds
