General Information on the SINUMERIK 840Di sl
1.1 Overview of SINUMERIK 840Di sl
PROFIBUS DP X102 interface
Unlike the PROFIBUS DP interface (X101), interface (X102) can only be accessed via the
PLC. As a result, no drives and no NC I/Os can be operated via this interface.
The interface (X102) can also be operated as an MPI interface. However, using the MPI-
communication with SINUMERIK 840Di sl with the present version is no longer
recommended.
MCI board extension slot variation (option)
A maximum of four fast digital I/Os, two sensing probes and two handwheels each can be
connected using the optional MCI board extension slot variant. Either differential or TTL
handwheels can be operated.
The module is inserted into a slot in the PCU and is connected to the MCI board via a ribbon
cable.
Digital drives
SINUMERIK 840Disl is available with the components from the new SINAMICS range of
drives offering the following characteristics:
● SINAMICS S120
The drive components from the SIMODRIVE range of drives offering the following
characteristics can also be used:
● SIMODRIVE 611 universal and universal E with option module Motion Control with
● SIMODRIVE POSMO CD/CA
● SIMODRIVE POSMO SI
● SIMODRIVE POSMO A (not suitable for interpolatory procedures)
Note
SINAMICS S120 and SIMODRIVE drives cannot be operated in parallel on a
SINUMERIK 840Di sl.
Analog drives
To operate drives with an analog setpoint interface via PROFIBUS, the following interface
module is available:
● ADI4 (Analog Drives Interface for 4 Axes)
I/Os
For use as distributed I/Os, the module range SIMATIC DP ET 200 (for connection
conditions, see SIMATIC Documentation) as well as the I/O Module PP 72/48 are available.
