Section 4. Setting up Datalogger Networks
Enabled check box for those dataloggers which should be enabled for call-
back.
Extra Response Time – LoggerNet is preconfigured to allow time for
responses based on type of device and baud rates. In this field, specify only the
additional time that LoggerNet should delay before terminating the
communications link if there is no response from the serial port. Additional
time may be needed in instances where the communications link is noisy or
network traffic is heavy. If extra response time is needed, it is typically set to 1
or 2 seconds.
Delay Hangup – The amount of time, in seconds and milliseconds, that
LoggerNet should delay before hanging up the link to the device. If a new
command to the device is issued before the delay has expired, communication
will not be terminated.
COM Port Communication Delay – The amount of time, in milliseconds,
that LoggerNet will wait after opening a communication port and before
sending data to the device. This can be useful when addressing drivers that
require a short delay before accepting data (such as an IRDA port driver).
LoggerNet waits a certain amount of time for a response from
each device in a communications path. The extra response times
defined for the communications link are cumulative. Therefore,
the amount of time spent waiting for a device to respond is the
sum of all Extra Response Times defined, plus the default
response time for each device in the link. Add only the
minimum time necessary since very long response times can
delay other scheduled events while waiting for a device that is
not responding.
NOTE
4.2.4.2 IPPort (Internet Protocol Serial Port)
Like the standard serial port, configuration for the IPPort has only Hardware
and Notes tabs. Following is an explanation of each of the fields on the
Hardware tab.
Standard
Communications Enabled – Before communication can take place, all
devices in the chain must be enabled. When this box is selected, the Internet
protocol serial port is enabled for communication.
Internet IP Address – In this field, enter the TCP/IP address and port through
which LoggerNet will communicate with the datalogger network. The address
is entered in the form ###.###.###.### for an IPv4 address or
[XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX] for an IPv6
address. (Alternately, a valid machine name can be entered.) The port is in the
form of :####. A typical IPv4 entry might be 123.123.123.123:1024. A
typical IPv6 entry might be [2620:24:8080:8600:85a1:fcf2:2172:11bf]:1024.
