Linking to PayPal cash plus account

I am not sure if I understand your query correctly. As I know, the PayPal cash or PayPal cash plus account can be linked to your personal PayPal account to hold a balance in the account and use the balance for your transactions. I think integrating with PayPal standard using your personal account should be fine to use with your PayPal cash plus account. 

If you are referring to something different, please let us know. We will be happy to help.
