PROFIBUS Module ID [BFM #26]
This BFM shows the ID code that the PROFIBUS User Organization (PNO) has issued to the 32DP : F332h.

Slave Address [BFM #27]
This BFM shows the actual slave address. When changing the slave address with a TO instruction, users
must write the new address value (0 - 126
match the projected DP address.
When the slave address is changed more than once in 5 seconds, the "Consistency Error" (BFM#29 Bit5) and
"Change Slave Address EEPROM Error" (BFM#37 Bit10) appear, and the 32DP latches the latest valid
address. For changing the slave address via SSA-telegram, the valid address setting range is (0 to 125
When the new address value is outside the range (0 to 126
the 32DP latches the latest valid address. The slave address can only be changed when the slave is in STOP
mode (BFM#20 Bit0 = OFF) with the "Address Change Impossible Flag" set to OFF (BFM#25 Bit8). When the
user changes the slave address with the "Address Change Impossible Flag" set to ON (BFM#25 Bit8), the
"Consistency Error" (BFM#29 Bit5) and "Change Slave Address EEPROM Error" (BFM#37 Bit10) appear.

User Diagnostics [BFM #28]
By writing to this BFM, the 32DP can send user-diagnostic data with high priority to the DP-Master. The data
from this BFM is handled as the extended diagnostic data by the DP-Master. When using this functionality,
users need to define the meaning for each bit. This functionality is compatible to the FX
32DP maps this BFM to BFM#1307.
