Appendix A.2. Extending the Event Table
New event causes may be added to the Event Table and the index value or category of existing event causes modified by adding a section to the configuration CSV file. The examples below illustrate this:
Example 1: Index value of 'Trouble' is updated to a new value of 100
Driver_Table |
|
|
|
Event_Type_Description, | Event_Type_Index_Value, | Event_Type_Category , | Protocol |
TROUBLE, | 100, | 4, | FCI_7200 |
Example 2: New Entry is added
Since it has been added as category=3, only MD's with 'Event Type' set to Alarm or ANY will capture messages with this event description
Driver_Table |
|
|
|
Event_Type_Description, | Event_Type_Index_Value, | Event_Type_Category, | Protocol |
DESTROYED, | 51, | 3, | FCI_7200 |
For categories use the following values 'Other' = 1
'Fault' = 2 'Alarm' = 3 'Trouble' = 4
Appendix A.3. How Data is stored
All messages less than 102 characters long are discarded. All other messages are processed as follows:
•The driver determines if the message is a Zone, Relay, Loop, Sensor, Module or Panel message.
•The driver finds all Map Descriptors with matching ‘Point Type’ parameters.
•The event category is determined.
•Map Descriptor selection is refined based on whether the ‘Event Type’ matches or has been defined as “Any:
•The driver determines the Loop. Relay, Zone, Sensor and Module numbers from the message and refines its selection of Map Descriptors by selecting those that match the values determined from the message.
•The selected Map Descriptors are now used to determine a data array and offset at which to store the data.
•Finally the driver checks the ‘Store As’ parameter. If it hasn’t been specified then ‘Index Value’ storage is assumed. If it has been specified as ‘Bits’ then the driver will perform ‘Bit Storage’. In cases where the Map Descriptor has both a primary and secondary Data Array, the driver will use ‘Index Value’ storage using the primary data array and ‘Bit Storage’ using the secondary array.
