Using RSNetWorx and the
Programming Software
The I/O configuration portion of the programming software generates
configuration data structures and tags for that module, whether the module is
in a local or remote chassis. A remote chassis, also known as networked,
contains the module but not the module's owner-controller.
After creating the module, you can write specific configuration in the module's
data structures; you must access the module tags to change information in the
data structures. This process is explained in detail in Chapter 5,
Configurable Flowmeter
Application-specific configuration data is transferred to the controller
IMPORTANT
during the program download and sent to the module during the initial
powerup. After module operation has begun, you must use ladder logic
and message instructions to make configuration changes.
CFM Modules in Local Chassis
Configurable flowmeter 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 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 modules:
1. Configure all 1756-CFM modules for a given controller by using
programming software and download that information to the controller.
2. If the configuration data references a module in a remote chassis, run
RSNetWorx software.
RSNetWorx software must be run whenever a new module is added to a
IMPORTANT
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.
