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 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 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 For example, if outdated ControlNet configuration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 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 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:
Download from both RSNetWorx and RSLogix 5
You can download the ControlNet configuration information from
RSNetWorx and the remaining controller information from
RSLogix 5.
