The General tab supplies information about the scanner. Choose the
Module tab and choose
Upload on the Scanner Configuration screen.
Once the upload is complete you’ll return to the Module tab.
You should accept the defaults except for the 1756-DNB slot number.
For this example, the slot number for the 1756-DNB in its
ControlLogix chassis is 1 (the default).
After modifying the chassis slot number, choose Download to
Scanner . This will ensure that the correct I/O addresses are displayed
under the Input and Output tabs.
Now choose the Scanlist tab. To add the 1769-ADN to the 1756-DNB
scanlist, choose the 1769-ADN shown in the Available Devices box on
the left. Choose the single right arrow between the Available Devices
box and the Scanlist box. This moves the 1769-ADN to the 1756-DNB
scanlist.
When you choose Edit I/O Parameters , you’ll see this screen.
Polled connection is the default
1
. You could choose to enable a
Change of State/Cyclic connection, but we won’t be using that in this
example. For more information on connection types, refer to the
Chapter 2.
Rx (receive) and Tx (transmit) sizes default to the Total Input and
Output bytes from the 1769-ADN summary page. For this example,
52 is the Rx size and 18 is the Tx size.
Choose the Every Scan poll rate. Refer to the 1756-DNB
documentation for a complete description of Every Scan and
Background Poll Rates.
1 Refer to Appendix C for some important system characteristics when using the polled mode (minimum
inter-scan delay I.D. for polled connections).
