6.1.11. ICMP monitoring modes
The DAEnetIP2 module supports two way (incoming/outgoing) mode for
monitoring via receiving/sending ICMP Echo Request and ICMP Echo Reply packets.
With this function the DAEnetIP2 module can be used as a device for active
monitoring of networks and networks devices. The DAEnetIP2 module performs and
restart pulse if there is not answer. The common parameter "Timeout" (in minutes)
must be given to determine the timeframe when the request/answer must be
received. If the timeout elapses then the i/o ports are reset.
Incoming ICMP monitoring
When the incoming ICMP monitoring mode is
enabled, the DAEnetIP2 module expects ping in the given timeout.
IMPORTANT!
If there is very big traffic in the network it is absolutely possible the incoming ping to
be not received. That's why it must be sent 5-10 ping requests.
Outgoing ICMP monitoring
During outgoing monitoring the DAEnetIP2 module
generates ping to the given IP address and expects answer within the given
timeframe. The request generating is performed several times in minute.
The both ICMP modes use one shared parameter "timeout" however they have
separate timers.
Restart Target Device
To restart external device (via relay driver) during
monitoring mode it is used special pin "Target RST" (look at the i/o port table). In this
way it is possible restarting of different electrical appliances (120/220VAC including).
From firmware version 4.097 it is possible to copy that signal to DAEnetIP2 - P5. The
restart of external devices may be started/stopped by the user. The restart pulse with
may be set by the user: (from 0 up to 32767 )x250ms.
The restart may be done manually via the following commands:
SNMP: Changing bit cfgMode.0; cfgResetPulse.0, pctrlRestart.0
(read-only), cfgP5DupRST.0
Web: Menu „Setup->Restart external device”, „Setup->External device restart pulse
width”, „I/O ports -> Force TargetRST”, „Setup->Duplicate 'TargetRST' on P5 pins
”
IMPORTANT!
The setting of pulse width greater than “Ping Timeout” will make the non-definition
(possible infinity) increasing of the restart pulse when there is not ping request or answer within the
given timeout. The reason is in the cyclic start of the pulse most frequently than it's width!
