Occasions to Upload the Event History
Note:
Each AC-115 controller can store up to 2000 events in its
internal memory. The internal memory of the controller is
cleared each time it uploads its event history to the PC
using the AC-115 PC software.
If the event history stored within an AC-115 controller’s internal
memory is not uploaded, the internal memory will eventually
become full. When the controllers’ internal memory is full and
new events occur, the oldest event in the internal memory is
deleted and the new event is stored in its place. This is called
Event Overflow.
When Event Overflow occurs, some events are lost due to a
lack of internal memory in the AC-115 controller. The lost data
will never appear in the PC software’s database and will
therefore not appear in any of the reports.
In order to prevent Event Overflow, each controller in your AC-
115 must have its event history uploaded to the PC software’s
database periodically.
There are two methods to upload the event history from the
AC-115 controllers in your network: manual and automatic
uploading.
Manual or Automatic Upload?
Note:
Manual Uploading has been designed for AC-115
networks that do not have a lot of event traffic and will
therefore not reach an Event Overflow condition quickly.
These networks usually do not have a dedicated PC that
can stay online and connected with the AC-115
network. A user must periodically initiate the Event history
upload sequence from the PC.
Automatic Uploading has been designed for AC-115 networks
that have a lot of event traffic. This is where an AC-115 can
achieve an Event Overflow quickly. Each AC-115 in the
network can be programmed to upload its event history
periodically. Automatic Uploading requires that your PC is
connected to the AC-115 network and online at all times
waiting to receive the event history from the controllers.
