When comparing these keywords to the data in the Status field of the message the driver only
compares the first three characters. The comparison is case insensitive.
Adding a New Status Type
The fragment of a CSV file displayed below illustrates how to change the value associated with
‘BUS’ to 9 and adds two new Status types, Fred and Ginger.
There is a limitation in the use of new status types. They can only be stored using map
descriptors with the Data_Type set to ‘Any’.
The driver can store a maximum of 100 status types. The maximum length of the string is 9
characters.
6.4 When do Data Arrays get cleared (Reset)
When the Gamewell Panel is reset then the driver is able to clear the arrays. The way that the
panel works is that when a reset is performed send the following message
Status:NORMAL 08/31/95 16:23
System Idle
After this message the panel then sends messages for all points that are not in a normal state.
The driver uses the parameter ‘Clear_On_Reset’ to determine what gets cleared. If a map
descriptor has this parameter set to ‘Yes’ then the arrays elements controlled by the
Data_Array_Offset and the Length are set to zero.
This provides a good technique of synchronizing the panel and the FieldServer. When you
restart the FieldServer you should push the reset button on the panel so that the panel sends
messages for all points that are not in a normal state. If you don’t do this, and some points are in
a not-normal state then the FieldServer will not know about them until their state changes This is
potentially dangerous.
6.5 Action Types
Typically messages from the panel are contain not only the status of a point but also describe the
action that caused the state to change.
