7.2.3 Configuration of the scan data talker map

The scan data talker map is managed in the configuration as shown in Figure

7-7.

The scan data talker map displays the lower 8 bits of the sending station

address that is using the corresponding scan data block. Scan Block No.

Sending Station Address contains the address of the sending station using the

scan block.

Scan Block No. Overlapping Source Address contains the address of the sending

station when two or more stations are sending to the scan block.

In the scan data talker map, the address of the sending station is set when

sending to the block is detected. The sending station information remains set

until it is cleared to zero.

The scan data talker map indicates whether the block has detected sending

one or more times after the scan data talker map is cleared to zero.

Note

• When clearing the scan data talker map to zero, be careful not to clear other areas by

mistake.

If no sending is detected after the scan data talker map is cleared to zero, the

sending station address and overlapping source address remain zero. If there

is only one station sending to the block, the sending station address contains

the address, and the overlapping source address is zero.

If there are two or more stations sending to the block, the sending station

address and overlapping source address contain the address. In this case,

which station is sending by mistake depends on the user system. Determine

according to the system configuration.
