Appendix A.5. Optional Data Arrays
When optional parameters (EST_Alarm_DA, EST_Trouble_DA, EST_Supervisory_DA, or
EST_Monitor_DA) are used, the driver automatically separates the Alarm Trouble, Supervisory, and
Monitor bit from the incoming EST message and places the bit(s) in these Data Arrays at the same
offset as the incoming message. Other types can be stored in EST_Others_DA Data Array. Only
one Data type will be reported as active at a particular time; i.e. if Alarm is reported Driver will set
Alarm bit and reset corresponding bits from Trouble, Supervisory and Monitor Data Arrays. The Driver
does not correlate Other types with Alarm, Trouble, Supervisory or Monitor types. For different point
types the active bit has a different meaning. If the user is interested in the meaning, the
EST_Supervisory_DA Data Array should be configured. If the user is interested in the raw value of
the Active bit, the data array EST_Active_DA should be configured.
Appendix A.5.1. Relay Confirmation State
The driver can store the relay confirmation state of a point in a Data Array under the parameter
EST_Relay_Conf_DA parameter.
0 - Relay state is not confirmed; 1 – Relay state confirmed.
Appendix A.5.2. EST_Types_DA
If it is necessary to override the default Types and Category list (Appendix C.1) the
EST_Types_DA parameter should be used.
Example:
To put HEAT type into the “Monitor” category where all other defaults remain the same, preload
the data array as follows:
Preloads
Data_Array_Name ,Preload_Data_Index ,Preload_Data_Value ,Length
DA_Types ,2 ,4 ,1
Preload_Data_Index is the type of device and Preload_Data_Value holds the category for the
specified device type. The legal values for Preload_Data_Value are listed below
Alarm 1
Supervisory 2
Trouble 3
Monitor 4
Others 5
Appendix A.5.3. EST_Types_Update
If this parameter is not defined or is “yes”, the driver will update its internal driver list according
to the parameters preloaded under EST_Types_DA. If the parameter is set to “New List”, the
driver will use ONLY the parameters defined under EST_Types_DA and will not reference or
update the default list at all. The driver will therefore not store any data for types that do not
have preloaded categories.
Appendix A.5.4. DA_Bit_Name
The ”Acknowledge
5
” state of a point is stored under this Data Array if configured.
0 – Acknowledged or Acknowledge not required.
1 – Point is not Acknowledged yet. To Acknowledge the point change the value to “0”.

The EST3 panel is only able to send/accept Acknowledgement when the panel is in Proprietary Mode.
Contact EST (Edwards Systems Technology) for information on configuring the panel.
