Request table
The request table is an array of structures containing commands and states that apply to
individual fragment DBs. If you created fragments with the AWP_Start_Fragment (Page 637)
command of type "manual", the STEP 7 user program must control these pages through the
control DB. The request states are read-only and provide information about the current
fragment. You use the request commands to control the current fragment.
