PROFIBUS bus terminal controller BC3100
Parameterization
Besides the parameterization in the DP standard, manufacturer-specific
operating parameters (User_Prm_Data) can also be transferred with the
Set_Prm service. These are distinguished by the fact that they are
transferred once from the master to the slave during establishment of the
connection. User_Prm_Data overwrites the settings that have been made
by way of the configuration interface. If these settings are not to be
overwritten, User_Prm_Data must not be sent. The User-Prm_Data of the
bus terminal controller BC3100 is based on the following structure:
Byte No. Description
Byte 0 Bit 0: Start-Bit monitoring on (0) / off (1)
Bit 1: Stop-Bit monitoring on (0) / off (1)
Bit 2: Watchdog time base 10ms (0) / 1ms (1)
Bit 3-5: 0 (reserved for expansions)
Bit 6: Fail_Safe off (0) / on (1)
Bit 7: DPV1-MSAC_C1 connection disabled (0) / enabled (1)
Byte 1 0 (reserved for expansions)
Byte 2 0 (reserved for expansions)
Byte 3 0 (reserved for expansions)

Byte 5 Bit 1: diagnostics via 2-byte diagnostics interface (1)
Diagnostics via DP diagnostics (Slave_Diag) (0)
Bit 0, 2-7: 0 (reserved for expansions)
Byte 6 0 ( reserved for expansions)
Byte 7 Bit 0: auto reset on the terminal bus in the event of an error on
(1)/off(0)
Bit 1: automatic terminal diagnostics on(1)/off(0)
Bit 4: diagnostics of digital terminals is mapped to the process
image (0)/ is not mapped to the process image (1)
Bit 2,3, 5-7: 0 (reserved for expansions)

exchange/Clear_Data
1: affiliated terminal bus outputs change to 0
2: affiliated terminal bus outputs remain unchanged
Bit 2,3: Reaction to terminal bus error
1: affiliated DP inputs change to 0
2: affiliated DP inputs remain unchanged
Bit 4-7: 0 (reserved for expansions)
Byte 11 Max. DP diagnostic data length (value range 16, 24, 32, 40, 48, 56,
64)
