3-4 Understanding the ControlNet System Software
Download from both RSNetWorx and RSLogix 5 software
You can download the ControlNet configuration information from
RSNetWorx software and the remaining controller information from
RSLogix 5 software. When downloading the project from RSLogix 5
software, a dialog box appears and asks whether the ControlNet
configuration information stored in the RSLogix 5 project should be
downloaded.
With this approach, you will want to keep the existing ControlNet
configuration that is currently on the ControlNet PLC-5 processor.
Download from RSLogix 5 Software Only
You can download the entire program from RSLogix 5 software while
keeping the ControlNet configuration information up to date. When
downloading the ControlNet configuration information from
RSLogix 5 software, a dialog box appears and asks whether the
ControlNet configuration information stored in the RSLogix 5 project
should be downloaded.
With this approach, you will want to overwrite the existing
ControlNet configuration that is currently on the ControlNet PLC-5
processor with the ControlNet configuration information that is
stored in the RSLogix 5 project (.rsp) file.
The ControlNet configuration information in RSLogix 5 software is
kept up to date by uploading from the ControlNet PLC-5 processor
and by saving a new RSLogix 5 project (.rsp) file following every
save performed in RSNetWorx software, or following an RSNetWorx
project download if a save was performed off-line.
Important: This approach simplifies the download to a single
operation, however it requires the maintenance of keeping the
RSLogix 5 project (.rsp) file up to date with the current ControlNet
network configuration information for every PLC-5 processor on the
ControlNet network. To do this, you must perform the RSLogix 5
upload and save for each and every save performed in RSNetWorx
software, even if no ControlNet configuration information changed
for any ControlNet PLC-5 processor. This is required because a
network keeper signature is reevaluated every save and is unique for
every save. The network keeper signature is downloaded to every
keeper-capable device on the ControlNet network.
Using RSNetWorx Software to Perform Verification Activities
After a Download or Save in RSNetWorx Software
We recommend that you perform two verification activities following
a download or save operation in RSNetWorx software:
• Verify Keeper Signatures
• Verify Scanner Signatures
