Figure 6.6: Coding User_Prm_Data_Not/_Okay_Cmd

If an additional Set-Param telegram is supposed to be received in the meantime, the signal ‘Prm_Conflict’ is is returned for the acknowledgement of the first Set_Param telegram, whether positive or negative. Then the user must repeat the validation because the SPC3 has made a new Prm buffer available.

6.2.3 Check_Config (SAP62)

The user takes on the evaluation of the configuration data. After SPC3 has received a validated Check_Config-Telegram, SPC3 exchanges the Aux-Puffer1/2 (all data bytes are entered here) for the Cfg

buffer, stores the input data length in ‘R_Len_CfgData,’- and generates ‘New_Cfg_Data-Interrupt’.

The user must then check the ‘User_Config_Data’ andeither respond with ‘User_Cfg_Data_Okay_Cmd’ or with ‘User_Cfg_Data_Not_Okay_Cmd’ (acknowledgement to the Cfg_SM). The net data is input in the buffer in the format regulation of the standard.

The user response (User_Cfg_Data_Okay_Cmd or the User_Cfg_Data_Not_Okay_Cmd response) again takes back the ‘New_Cfg_Data’ interrupt and may not be acknowledged in the IAR.

If an incorrect configuration is signalled back, various diagnostics bits are changed, and there is branching to ‘Wait_Prm.“

For a correct configuration, the transition to ‘DATA_EX’ takes place immediately, if no Din_buffer is present (R_Len_Din_Puf = 00H) and trigger counters for the parameter setting telegrams and configuration telegrams are at 0. Otherwise, the transition does not take place until the first ‘New_DIN_Puffer_Cmd’ with which the user makes the first valid ‘N buffer” available. When entering into ‘DATA_EX,’ SPC3 also generates the ‘Go/Leave_Data_Exchange-Interrupt.

If the received configuration data from the Cfg buffer are supposed to result in a change of the Read-Cfg- buffer ( the change contains the data for the Get_Config telegram), the user must make the new Read_Cfg data available in the Read-Cfg buffer before the ‘User_Cfg_Data_Okay_Cmd” acknowledgement. After receiving the acknowledgement, SPC3 exchanges the Cfg buffer with the Read-Cfg buffer, if ‘EN_Change_Cfg_buffer = 1’ is set in mode register1.

During the acknowledgement, the user receives information about whether there is a conflict or not. If an additional Check_Config telegram was supposed to be received in the meantime, the user receives the ‘Cfg_Conflict” signal during the acknowledgement of the first Check_Config telegram, whether positive or negative. Then the user must repeat the validation, because SPC3 has made a new Cfg buffer available.

The ‘User_Cfg_Data_Okay_Cmd’ and ‘User_Cfg_Data_NotOkay_Cmd’ acknowledgements are read accesses to defined memory cells (see Section 2.2.1) with the relevant ‘Not_Allowed’, ‘User_Cfg_Finished,’ or ‘Cfg_Conflict’ signals (see Figure 3.7). If the ‘New_Prm_Data’and ‘New_Cfg_Data’ are supposed to be present simultaneously during power up, the user must maintain the Set_Param and then the Check_Config. acknowledgement sequence.
