3-4 Understanding the ControlNet System Software

When downloading the project from RSLogix 5, 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 Only

You can download the entire program from RSLogix 5 while keeping

the ControlNet configuration information up to date.

When downloading the ControlNet configuration information from

RSLogix 5, 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 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, 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,

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 to Perform Verification Activities After

a Download or Save in RSNetWorx

We recommend that you perform two verification activities following

a download or save operation in RSNetWorx:

• Verify Keeper Signatures

• Verify Scanner Signatures
