CFM Modules in Local Chassis
CFM modules in the same chassis as the owner-controller are ready to run as
soon as the configuration data has been downloaded.
CFM Modules in Remote Chassis
You must run RSNetWorx™ software to enable CFM modules in the
networked chassis. Running RSNetWorx software transfers configuration data
to networked modules and establishes a Network Update Time (NUT) for
ControlNet. The NUT is compliant with the desired communications options
specified for each module during configuration.
Follow these general guidelines when configuring CFM modules:
1. Configure all CFM modules for a given controller using RSLogix 5000
software and download that information to the controller.
2. If the CFM configuration data references a module in a remote chassis,
run RSNetWorx software.
IMPORTANT
RSNetWorx software must be run whenever a new
module is added to a networked chassis. When a module is
permanently removed from a remote chassis, we
recommend that RSNetWorx software be run to optimize
the allocation of network bandwidth.
