By using the device select field, you can view the mapping of each device
into the data table inside the SLC-500 processor.
Note: The RediSTA TION, photoeye, and DeviceLink are all sharing the
same data field. This shows the versatility of the DeviceNet Manager
software for mapping device data. The scan list is the same as what is
actually loaded in the 1747-SDN of your seminar. These bits will be
monitored later in the SLC-500 using RSLogixTM 500 programming
software.

Notice that the RediSTATION operator interface’s red light starts
blinking, the DL10 Dataliner display shows a PHOTO OFF
DEVICENET message, and the scanner display alternatively blinks
between 72 and 07. Also, the green status indicator on the photoeye
should be blinking green.
The reason for the above warning messages is that the 1747-SDN scanner
module is expecting a slave device (the photoeye) at node address 7. By
changing the node address to 55, node 7 has “disappeared”. This
disappearance sets a fault bit in the scanner’s memory , which can be read
by the SLC processor to display fault diagnostics, such as flashing a red
light or displaying a text message. Also, the photoeye with its new node
address no longer has a master to communicate with thus causing it to
flash its green communication status indicator.
Now let’s return the photoeye to node address 7.
