6.15 Allocated Group ID Number [BFM #34]
6.15
Allocated Group ID Number [BFM #34]
BFM Access : Read Only
This BFM shows the groups including the 32DP.
The DP-Master can allocate the 32DP to two or more groups simultaneously. When the BFM#34 = 0, the DP-
Master has not allocated the 32DP to any group.

DP-V1 Communication Parameter [BFM #35]
BFM Access : Read Only
This BFM shows the 32DP’s communication status. Depending on the module status, this BFM content varies
as follows.
*1.
BFM#35 Bit2 corresponds to BFM#1299 Bit0.
→
For details on BFM#1299, refer to Section 6.35
*2.
If any of these bits is ON, the 32DP aborts the acyclic service and sends the corresponding error to
the DP-Master.
