Bit 0

MAC_Reset

 

 

 

 

 

 

After it processes the current request, the SPC3 has arrived at the offline state (through

 

 

 

 

 

setting the ‘Go_Offline bit’ or through a RAM acces violation).

 

 

Bit 1

Go/Leave_DATA_EX

 

 

 

 

 

 

The DP_SM has entered or exited the ‘DATA_EX’ state.

 

 

Bit 2

Baudrate_Detect

 

 

 

 

 

 

The SPC3 has exited the ‘Baud_Search state’ and oundf a baud rate.

 

 

Bit 3

WD_DP_Control_Timeout

 

 

 

 

 

 

The watchdog timer has run out in the ‘DP_Control’ WD state.

 

 

Bit 4

User_Timer_Clock

 

 

 

 

 

 

The time base for the User_Timer_Clocks has run out (1/10ms).

Bit 8

New_GC_Command

 

 

 

 

 

 

The SPC3 has received a ‘Global_Control telegram’with a changed ‘GC_Command-

 

 

 

 

 

Byte,’ and this byte is stored in the ‘R_GC_Command’ RAM cell.

 

 

Bit 9

New_SSA_Data

 

 

 

 

 

 

The SPC3 has received a ‘Set_Slave_Address telegram’ and made the data available

 

 

 

 

 

in the SSA buffer.

 

 

 

Bit 10

New_Cfg_Data

 

 

 

 

 

 

The SPC3 has received a ‘Check_Cfg telegram’ andmade the data available in the Cfg

 

 

 

 

 

buffer.

 

 

 

Bit 11

New_Prm_Data

 

 

 

 

 

 

The SPC3 has received a ‘Set_Param telegram’ andmade the data available in the

 

 

 

 

 

Prm buffer.

 

 

 

Bit 12

Diag_Puffer_Changed

 

 

 

 

 

 

Due to the request made by ‘New_Diag_Cmd,’ SPC3 xchanged the diagnostics buffer

 

 

 

 

 

and again made the old buffer available to the user.

 

 

 

Bit 13

DX_OUT

 

 

 

 

 

 

The SPC3 has received a ‘Write_Read_Data telegram’ and made the new output data

 

 

 

 

 

available in the N buffer. For a ‘Power_On’ or fora ‘Leave_Master,’ the SPC3 deletes

 

 

 

 

 

the N buffer and also generates this interrupt.
