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.
