5.3.4.Map Descriptor Example.

This example shows a number of server Map Descriptors used to define a table called ‘DISPLAY’. If a client sends a read table request the driver responds by sending all the appropriate data for every Map Descriptor with the same table name (provided that the node’s match).

All the server Map

If the value of the array named

Descriptors are

TABLE_DISPLAY, offset 10 is 1

passive.

then the FieldServer will report he

 

FLTSTAT variable as DIRTY. If it

 

is zero then the variable’s state

 

will be reported as clean.

By using the NUMERIC keyword, the driver is told to report the value of the variable HCAP as a number. Thus the driver sends the value of the array named TABLE_DISPLAY offset 9 to the client.
