Understanding the ControlNet System Software 3-3
Under these circumstances, consider the following guidelines:
• when configuring intelligent modules over ControlNet, any
configuration changes should be performed via a module’s
respective applet in the I/O configuration utility. This will ensure
that the edits are written to both the data table and the
RSNetWorx project (.xc) file.
• if you must configure an intelligent module over ControlNet via
program logic, you must then upload the online network
configuration in RSNetWorx software to synchronize the contents
of the data table with the RSNetWorx project (.xc) file. This will
ensure that the I/O configuration utility applet will contain
current information the next time it is launched.
Uploading and Downloading Software Projects
Considering that both RSLogix 5 and RSNetWorx software can
upload and download the ControlNet configuration information, you
must make sure that both the RSLogix 5 project (.rsp) file and the
RSNetWorx project (.xc) file contain the same ControlNet
configuration information. For example, if outdated ControlNet
configuration information is present in the RSLogix 5 project (.rsp)
file, a download of the RSLogix 5 project may download ControNet
configuration information that does not match the current ControlNet
network.
There are two reasons why the RSLogix 5 project (.xc) file contains
ControlNet configuration information:
• the RSNetWorx tool can only download to the entire ControlNet
network. For example, in an application where a single
ControlNet PLC-5 needs to have its program downloaded,
RSNetWorx software will attempt to download all nodes on the
ControlNet network. This will be time-consuming and require
that all ControlNet PLC-5 processors on the ControlNet network
be placed in PROGRAM mode.
• the RSLogix 5 software download can download everything to a
ControlNet PLC-5 in a single download. If the ControlNet
configuration information was not contained within the RSLogix
5 project, both an RSLogix 5 project download and an
RSNetWorx project download would be required.
Verify that ControlNet PLC-5 Configuration Matches Network
Information
To make sure that the ControlNet configuration information
downloaded to the ControlNet PLC-5 processor matches the current
ControlNet network information, follow one of these procedures:
