0846h TS_Adr_Register

6..0

Profibus station Address of the DPC31 (this slave)

0847h Real_No_Add_Change

7..0

This parameter indicates whether the DP slave address may be changed

at a later time. After reset, the slave firmware must set this parameter if it

permits the Set_Slave_Address SAP.

0 = Address may be changed

Otherwise = Address may not be changed

If the DPC31 then receives a Set_Slave_ Address message, it enters the

current value here.

0848h WD_Baud_Control_Val

7..0

The root value for baudrate monitoring is parameterized.

0849h Interframe GAP_Time

5..0

The Interframe GAP time (4...32 bits) is to be parameterized here for

synchronous bus physics.

084Ah DPS_User_Wd_Val

7..0

In the DPS_Mode, the user is monitored with an internal 16-bit watchdog

timer. The timer is decremented every 10 msec and must be reset by the

user cyclically to the start value ’DPS_User_ WD_Value

15..0

’. Resetting,

enabling, and disabling the timer is initiated with ’DPS_User-Wd’ request

in the Instruction_Queue.
