AVENTICS | Bus Coupler AES/Valve Driver AV, PROFIBUS DP | R412018135–BAL–001–AG
Submodule status: This diagnostic message is only generated by the bus coupler. The bus coupler
checks the status of each module and can also report the following errors:
Error in electronics power supply (UL)
Error in the actuator voltage (UA)
Backplane error
The module status message consists of 22 bytes.
The header for the module status consists of 4 bytes.
Table 14: Assignment of bytes 1-4 (header)
Byte no. Meaning
Byte 1 Length of the diagnostic block (0x16)
Byte 2 Status type (0x82)
Byte 3 0
Byte 4 0
In the following 16 bytes, the statuses of the individual modules are listed. Each module has 2 bits
of status information. the meaning of the statuses of bit 0 and bit 1 can be found in Table 15 taking
module no. 1 for example.
Table 15: Assignment of bytes 5-20 (module status)
Byte no. Bit no. Slot
Byte 5 Bit 0–1 Module no. 1
Bit 2–3 Module no. 2
Bit 4–5 Module no. 3
Bit 6–7 Module no. 4
... ... ...
Byte 20 Bit 6–7 Module no. 64
This is followed by 2 more bytes added by the bus coupler. In these bytes, the bits have the following
meanings:

Byte no. Bit no.
Byte 21 Bit 0
Bit 1
Bit 2
Bit 3
Bit 4
Bit 5
Bit 6
Bit 7
Byte 22 Bit 0
Bit 1 Bit 0 Meaning
0 0 Module is configured correctly
1 0 An incorrect module is configured at this
module position, or the module has not been
configured at all.
1 1 A module is configured at this module
position, but no module is present (there are
more modules configured than physically
present).
