Keeper Configuration - Automatic Keeper Crossload
The 1756-CN2 series B module is a keeper capable module. This
means that, if the module has a valid configuration and has the
lowest address among the keeper capable nodes on the network, it
becomes the Master Keeper. The Master Keeper is the node that
distributes network configuration information to other nodes as the
network is formed or as nodes are added to the network.
When the module is first removed from the box, or is reset to the
original factory settings, it will automatically attempt to crossload
configuration information from the current Master Keeper. If a Master
Keeper with a valid network configuration is present on the network,
the configuration crossload will succeed; no user configuration is
needed. However, if a Master Keeper does not exist, or does not have
a valid network configuration, you must use RSNetWorx for
ControlNet to download the network configuration information.
IMPORTANT Do not use the 00 switch setting during normal module operation.
