Example 3:x or 4:x Register Transfer
The following example shows a typical command used to retrieve a special
function command from the Quantum. In this example, registers 400500 to
400563 from the Quantum will be used to provide the information required by the
module.
The following section shows the functions that may be performed by using the
Command Function 3.
5.4.4 Read Status (9250)
Use block 9250 to request the module's status data. The module supports a
buffer queue of 99 events per data type. The application can verify the status of
the queue (free space in the queue) through the module's status data (Block
9250). When the queue is full, the module will delete the older event in the queue
if a new event is received.
There are two ways to request status data:
 Read the data in the database, starting at word 4000. Refer to Error Status
Table (page 176) for detailed information.
 Request the entire status block with a block 9250 block request.
The module responds to a valid block 9250 request with a block containing the
requested status data. The status data area for the module starts at address
4000 in the database.
The format of this block is shown in the following table.
