History
The IMS-4000 stores both datalog and eventlog history internally. The datalog is a time-stamped
collection of input values that can be used to view and graph environmental conditions over time.
It can also store the status of IP devices. The user can choose which inputs or IP alarms are stored
and specify the overall sampling rate. Care should be taken to select the number of inputs and sam-
pling rate accordingly, since large amounts of data can potentially be logged. The more data being
logged, the faster the history log will fill up.
The eventlog contains time-stamped messages that describe activities performed by the unit such as
alarm detection, user logins, telephone calls, and alarm acknowledgement. The eventlog history is
useful when you want to review the historical events monitored and performed by the IMS-4000.
When a user goes online, information for both the datalog and eventlog history is automatically
retrieved and stored in a database on a user-specified hard disk. This can be a drive on your own
computer or a network server. While the program defaults to saving the history database on your
local drive, if the system will be used by many users it may be advantageous to store the database
on a network drive. To specify the drive for saving History information click File, then Options
from the main menu. A sample screen is shown below:

To change the location for storing the History database, click the folder button on the right side of
the screen and choose a new location. The location you select will be displayed to the left.
Use the up or down buttons to select the amount of history to be viewed when accessing the History
option through the right-click menus in the ConsoleView software. This provides a quick view
of the history for a particular Input or Profile. The default time is 24 hours (1 day). Clicking the
arrows will increase or decrease the data time by days.
Analog input values will automatically be graphed when viewing History through the right-click
menus of the ConsoleView software. You can choose to have the graphed data displayed as a line
graph or simply show the discrete data points.
You can also deselect the Automatically Update buttons if you don’t want the Datalog or Eventlog
to download each time you connect. If you are using a dialup connection, you may want to disable
these functions to speed up the software loading process. (You can manually download the logs as
desired by right-clicking on History in the menu tree.)
