DG1
Overview of which slave signaled diagnostics data. This output is
bit-coded. Every bit is assigned to a slave with its Profibus
address.
Bit 3 of the 32 bit is, for example, assigned to the slave with
Profibus address 3.
Comment: The bits 0 up to and including 2 are always 0 as the
associated addresses (0 to 2) should be reserved for the DP
master, for a PG and an OP.
For a more detailed description, refer to the user manual
"FM 458-1 DP", chapter "Configuring", section "PROFIBUS DP
coupling".
DG2
Overview of which slave had signaled diagnostics data. This
output
is bit-coded. Every bit is assigned to a slave with its Profibus
address. The bit 0 of the 32-bit word is, for example, assigned to
the slave with Profibus address 32.

"FM 458-1 DP", chapter "Configuring", section "PROFIBUS DP
coupling".
DG3
Overview of which slave had signaled diagnostics data. This
output
is bit-coded. Every bit is assigned to a slave with its Profibus
address. The bit 0 of the 32-bit word is, for example, assigned to
the slave with Profibus address 64.

"FM 458-1 DP", chapter "Configuring", section "PROFIBUS DP
coupling".
DG4
Overview of which slave had signaled diagnostics data. This
output
is bit-coded. Every bit is assigned to a slave with its Profibus
address. The bit 0 of the 32-bit word is, for example, assigned to
the slave with Profibus address 96.

"FM 458-1 DP", chapter "Configuring", section "PROFIBUS DP
coupling".
DL1
Overview of with which slave data transfer took place. This output
is bit-coded. Every bit is assigned to a slave with its Profibus
address. For example, bit 3 of the 32-bit word is assigned to the
slave with Profibus address 3.
