Error Status Register [BFM #29 Bit0 to Bit13]
BFM Access : Read / Write
This BFM shows the 32DP’s error status. In the General Error (BFM#29 Bit0 = ON), the 32DP sends the data
from BFM#28 and #29 as diagnostic data to the DP-Master, while suspending the normal data exchange.
When turning the PLC from STOP to RUN, all BFM#29 Bits turn OFF except Bit3, 4, 12 and 13.
The 32DP maps this BFM to BFM#1308.
*1.
BFM#37 shows the error reason.

For details on BFM#37, refer to Section 6.18
*2.
BFM#38 shows the error reason.

6.13
Module ID Code [BFM #30]
BFM Access : Read Only
This BFM shows " 7150 " as the Module ID Code of the 32DP, given by its vendor.
6.14
Master Address [BFM #33]
BFM Access : Read Only
This BFM shows the DP-Master address on the DP network, where the 32DP exists. When the DP-Master
does not recognize the 32DP, this BFM value is 00FFh.
