Configuration Defined
Set mul(ticast) aaa.bbb.ccc.ddd
The multicast address must be set when using Facility Net. This command sets the
multicast address in a decimal notation form of aaa.bbb.ccc.ddd. Each three-digit
series is a value of 0-255 separated by a period (.) character. This address is unique to
the hardware it serves. An example of a valid multicast address is:
224.100.100.001
.
Set gat(eway) aaa.bbb.ccc.ddd
The gateway address is used when communicating across different networks. This
command sets the gateway address in a form of aaa.bbb.ccc.ddd. Each three-digit
series is a value of 0-255 separated by a period (.) character. Use gateway
000.000.000.000 if no gateway device is available on the network. An example of a valid
gateway address is:
010.255.000.060
.
Set ntp ddd.ddd.ddd.ddd
The
set ntp
command sets the NTP server IP (Internet Protocol) address. The values
ddd
represent decimal entries for each address octet (do not use leading zeros). This
setting will be saved after the
write
command is issued.
Set que(ue) x
When used with Facility Net, you can enter a data queue size in order to buffer data
while the unit is not connected.
Setting this parameter automatically saves the value and reboots the sensor.
The value of
x
can be set anywhere between 1 and 1440. The queue size to enter
depends on the specific application. In general, the value should be made large
enough to minimize data loss when disconnected, but not so large as to create
significant delays in the reception of real-time data when reconnected.
When a data queue size is set greater than one, the Airnet II 4-Channel particle sensor
will:
•
Continue sampling if it was initially started, and then disconnected
•
Queue up to the number of samples defined by the queue size
•
Unload the queued data in chronological order when reconnected
•
Periodically delete elements of the queue for which Facility Net has received the
data
When the queue size is set to one (1), the Airnet II 4-Channel particle sensor reverts to
a mode where there is no data queue, the unit reboots when disconnected and
parameters specific to batch processing are enabled.
Set mod x
The unit will run under one of three possible operational modes: PMS Operational
Mode, or Modbus TCP. When shipped from the factory, the unit is in the PMS
Operational Mode.
Setting this parameter automatically saves the value and reboots the sensor.
•
When the value of
x
is set to zero (0), the unit will reboot into the PMS Operational
Mode.
•
When the value of
x
is set to two (2), the unit will reboot into Modbus TCP mode.
Select the PMS Operational Mode for use with the calibration program.
