Configure the ControlNet Network Chapter 5
To replace a ControlNet module that has been configured and scheduled on the
ControlNet network, remove the existing module and insert a 1756-CN2/B,
1756-CN2R/B, or 1756-CN2RXT module. The module you are inserting must
be unconfigured or have a keeper signature of all zeros.
After being inserted and connected to the ControlNet network, the
unconfigured 1756-CN2, 1756-CN2R, and 1756-CN2RXT modules crossload
the appropriate configuration from the active keeper on the ControlNet network
and become configured with the appropriate keeper signature.
TIP To clear the keeper signature of a 1756-CN2, 1756-CN2R, or 1756-CN2RXT
module, complete these steps.
1.Disconnect the module from the ControlNet network and remove it from the
chassis.
2.Set the node address switches to 00.
3.Insert the module back into the chassis and wait for the status display to indicate
Reset Complete.
4.Remove the module and set the node address switches to the intended node
address.
5.Insert the module into the chassis.
