Allen-Bradley DeviceNet 1756-DNB - Setting Module Operational Parameters

3–4 Configuring Through DeviceNet Manager Software
Publication 1756–6.5.15 – July 1998
You see this screen.
The scan list editor title bar
indicates (in parenthesis)
where the data comes from
(file, project, DNB, or Who).
The Module Configuration screen allows you to set the
communication module’s operational parameters.
Setting the Module’s Operational Parameters
1. Enter the time the communication module waits between scans
(between 2 and 9000 milliseconds) in the Interscan Delay edit
box.
The default Interscan Delay is 10 milliseconds.
2. Enter the ratio of foreground to background polls (between 1 and
65535) in the Foreground to Bkgd Poll Ratio edit box.
The default poll ratio is 1.
Devices can be polled at a background rate instead of every scan.
Whether a device is polled every scan or at a background rate is
determined in the Edit I/O Parameters screen discussed on page
3–13. For example, if the value of 5 is set, the communication
module polls the selected device(s) once every five scans.
3. Set the loading options (files with an .sm5 extension):
A. To load data from your communication module’s non-volatile
memory, in the Load From field, choose DNB.
The screen is automatically updated with what was received
from the communication module.
B. Load data from a file in your PC, in the Load From field,
choose File.
