IM MW100-01E
5.2 Main Module Specifications
DHCP function: The IP address is automatically obtained from the DHCP server
SNTP function: Client function:
Acquires time information from the apecifi ed SNTP server
when the power is turned on, upon start of measurement, when
the SNTP client is turned ON, at a user-specifi ed time, and at a
specifi ed time interval.
When time information is acquired upon startup, measurement
start, and when the SNTP client is turned ON, the time is
not applied if the difference between the time of the MW100
and the server is 1 hour or more. When the time is acquired
at specifi ed time intervals, the MW100 time is corrected by
1 second at 10 second intervals. This is effective when the
shortest measurement interval within a unit is two seconds or
more. However, if the time between the server and MW100 is
different by 10 minutes or more, the time is not applied.
Server function:
Provides time information to the MW100 connected to the
network.
E-Mail function: Sends e-mail according to alarm activation/release, specifi ed
time intervals, fi le creation time, time at which free memory space
drops below specifi ed amount, time power turned ON, times
errors occur, and other times.
Two mail recipient locations can be set (multiple addresses using
up to 150 characters).
FTP function: Client function:
Transfer fi le containing measured, computed, thinned values,
recording log, and alarm summary on the CF card.
Recipient: Primary and secondary
Number of characters: Up to 64 characters, multiple
addresses
Transmission time: When the fi le is created
Transmission time shift: Delay the transmission time by the
specifi ed amount
0 to 10 minutes in unit of 1 minute.
The fi les are sent to the primary recipient fi rst, and if
transmission fails, they are sent to the secondary recipient.
If transmission to the secondary recipient also fails, the fi le is
held in memory (up to eighteen fi les that failed to be sent are
held) and transmission is retried after the next fi le is created or
when the power is turned on (assuming there are fi les in the
CF card). If transmission fails more than eighteen times, old
fi les are overwritten with new ones.
Server function:
Transfer or delete fi les according to commands from a PC.
HTTP function: Enables entry of settings on the MW100, starting and stopping
of measurement, computation, and recording, and real time
monitoring of measured and computed values using a Web
browser, as well as acquisition of CF card fi les using WebDAV.
