Hello STGBruce,
If you don't see in the the Hardware tab it might be that you don't have installed the components from the PLUS+1 Update Center, and you have the PLUS+1 GUIDE setting to not show folders that are empty.
The setting can be found here: PLUS+1 GUIDE > Setup > Options > Tabs. In the "Tabs Settings" you can uncheck the box "Hardware tab hides empty folders".
In PLUS+1 Update Center you have to select the components in your subscription, download and install them.
Click the "Edit" button in the top right corner, go to Content > Compliance Blocks > IO Modules. Save selection, button on bottom right. Refresh (F5) if needed and install.
I hope this works out.
