Section 4. Setting up Datalogger Networks

If you are using LoggerNet Admin or LoggerNet Remote 4.0 and

using the Connect Screen to connect to a remote server that is

running an older version of LoggerNet, the behavior will be

different than described above. When connecting to a LoggerNet

3.4.1 server, you will be disconnected with no advanced warning

when Max Time On-Line is reached. A message will be displayed

indicating that Max Time On-Line has been reached. When

connecting to servers older than LoggerNet 3.4.1, the behavior

will be variable. Generally, you will be disconnected at some

point, but the timing of the disconnect will not be predictable.

Maximum Baud Rate – Select the arrow to the right of this field to choose a

maximum baud rate for communication with this datalogger. Note that the

actual rate of communication may be limited by the capability of other devices

in the communications chain.

Beacon Interval – Routing devices in a PakBus network are capable of

“learning” about other devices in the network. To learn about other devices in

the network the router can be configured to send out a beacon, and any devices

in the PakBus network that can “hear” the broadcast will respond with an

identification message. The beacon interval is how often the computer will

send out a beacon to the PakBus network. If the PakBus Port is Dialed check

box is enabled, the beacon will not be transmitted at the specified interval

unless LoggerNet is actively communicating over the PakBus Port.

PakBus Verify Interval – The amount of time, in seconds, that will be used as

the link verification interval in the PakBus hello transaction messages. If no

communication has taken place during the specified interval, LoggerNet will

initiate a hello exchange with the datalogger. A verify interval of zero causes

LoggerNet to use a default verify interval of 2.5 times the beacon interval. If

the beacon interval is also zero, the default verify interval is 5 minutes.

The format for this field is 00 h(ours) 00 m(inutes) 00 s(econds).

Hardware Tab, Advanced
Extra Response Time – In this field, specify the additional time that

LoggerNet should delay before breaking the communications link if there is no

response from the datalogger. Additional time may be needed in instances

where the communications link is noisy or network traffic is heavy.

PakBus Address – This read-only field displays the address that has been

assigned to the PakBus port. In most instances, the LoggerNet server has only

one PakBus address that is used for all PakBus ports; however, if you want to

have multiple independent PakBus networks, you can set the PakBus address

for each port separately. Multiple PakBus ports can be assigned individual

addresses using the Options | LoggerNet PakBus Settings menu option.

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.
