Set the Communication Rate
The 1756-DNB scanner module supports the following DeviceNet network
communication rates:
• 125 Kbps
• 250 Kbps
• 500 Kbps
The factory default setting is 125 Kbps.
Change the communication rate by setting the rotary switch or
commissioning the 1756-DNB scanner module in RSNetWorx for DeviceNet
software.
Use the switch to select a specific communication rate. When the switch is set
to 3...9 (except for 888), you can configure the communication rate with
RSNetWorx for DeviceNet software. When all three switches are set to 8, the
1756-DNB scanner module will reset to factory default settings at powerup.
See Restore the Factory Default Settings on
page 15 for more information.
See the following table for switch settings.
ATTENTION Do not change the communication rate on an active network. Unpredictable
operation may result. In addition, the new communication rate does not take
effect until you cycle power to the 1756-DNB scanner module.
