Drive-Object Assignment For Profibus Connection - Siemens SINUMERIK 840D sl Commissioning Manual

Connection conditions
To ensure that the SMC40 Sensor Module Cabinet-Mounted is integrated into the topology
during the initial commissioning, you must absolutely observe the following rules:
● Connect at least one of the DRIVE-CLiQ interfaces X500/1 or X500/2 on the SMC40 using
DRIVE-CLiQ.
● Connect one EnDat encoder to the corresponding encoder interface X520/1 (to X500/1) or
X520/2 (to X500/2).
● Operate the SMC40 only in a star topology. The DRIVE-CLiQ X500/1 and X500/2 sockets
cannot be used for a series connection.
NOTICE
Display in the "Topology" dialog
The SMC40 is only integrated into the actual topology if the DRIVE-CLiQ interfaces X500/x
and the corresponding encoder interfaces X520/x are assigned.
Without a connected encoder, it is also not possible to subsequently integrate the SMC40 in
the topology.

Drive-object assignment for PROFIBUS connection

Drive object number
PROFIBUS telegrams (internal PROFIBUS, HW Config) are used to specify the process data
to be exchanged between the NC and the drives. The sequence of the drive objects
(configurable/configured using HW Config) involved in PROFIBUS process-data exchange is
defined via a drive-object list.
The drive-object numbers (DO numbers) can be viewed under "Commissioning > Machine data
> Control Unit MD/Infeed MD/Drive MD" in the component name line. An example of a Control
Unit name might be: "DP3.Slave3:CU_003 (1)". The DO number appears inside the brackets
"(...)".
List of drive objects
You usually configure eight drive objects (default setting): The drive objects have drive-object
numbers and are entered in parameter p0978[0...9] as a list of drive objects:
p0978[0] = 3
p0978[1] = 4
p0978[2] = 5
p0978[3] = 6
p0978[4] = 7
p0978[5] = 8
p0978[6] = 1
