How to get all the parameters for 1s standard exchange with an order site?

Question

1C

1. Where to get the file that should be downloaded in 1s from the site for exchanging orders, which will contain all the parameters for a specific 1s configuration, for example, for UT 11 and UNF 1.6, which can be used and forwarded, for example, VAT rate for goods
   
2. In the upload file from the site, you need to constantly add all orders in order to receive movement from 1c on them, as soon as I remove them from this file, 1c stops reporting information about them, and when added again, it creates a new order, is this normal work?
