6 PROFIBUS DP Interface
6.2.9 Get_Cfg (SAP 59)
The user makes the configuration data available in the Read_Config-Buffer.
For a change in the configuration after the Chk_Cfg telegram, the user
writes the changed data in the Config-Buffer, sets
‘En_Change_Cfg_buffer = 1’ (see Mode Register 1) and the VPC3+C then
exchanges the Config-Buffer for the Read_Config-Buffer. If there is a
change in the configuration data during operation (for example, for a
modular DP systems), the user must return with Go_Offline command (see
Mode Register 1) to WAIT-PRM.
