llooking for more detailed documentation XCD1

I am using the XCD1 Drive for a project and i was wondering if their is more documention for it. I'm looking for some documentation about how to install and setup all the different connection like e.g. how do i connect the XG41 (STO). Do i connect the the outputs to de digital inputs of the XG31? I am looking for that kind of information. 

I have found the following link with documentation: https://www.boschrexroth.com/en/xc/myrexroth/media-directory?p_p_id=3&p_p_lifecycle=0&p_p_state=normal&p_p_mode=view&p_p_col_id=column-1&p_p_col_pos=1&p_p_col_count=3&_3_vocabId_3825778=21919939&_3_cur=1&_3_vocabId_4354720=&_3_sortReverted=undefined&_3_keywords=xcd&_3_formDate=1614164333302&_3_groupId=0&_3_format=&_3_delta=30&_3_delta=30&_3_documentsSearchContainerPrimaryKeys=20_PORTLET_30490459%2C20_PORTLET_30387994%2C20_PORTLET_30387472%2C20_PORTLET_30387287%2C20_PORTLET_30124428%2C20_PORTLET_30078325%2C20_PORTLET_30059707%2C20_PORTLET_28912538%2C20_PORTLET_29782803%2C20_PORTLET_28938513%2C20_PORTLET_28910767%2C20_PORTLET_28957100%2C20_PORTLET_29764306%2C20_PORTLET_28925453%2C20_PORTLET_28996837&_3_vocabId_3833197=3833237&_3_vocabId_5334676=&_3_sortField=&_3_struts_action=%2Fsearch%2Fsearch&_3_applyFilter=false 

But I miss some details, only the pinlayout is given and the the actual functionality of the different connection, any help is greatly appriciated!
