8.2 Requirements
As a condition for creating a PROFIBUS configuration using the default configuration the
following components are required:
● SIMATIC STEP 7
● 840Di sl Rack
(A preconfigured SIMATIC 300 station for SINUMERIK 840Di sl. Part of the PLC basic
program)
● SlaveOM
(part of the scope of supply of a SINUMERIK 840Di sl: SIMATIC add-on software)
SIMATIC STEP 7
SIMATIC STEP 7 (option) is required in the following version or later:
● SIMATIC STEP 7 as of Version 5.3, Service Pack 2
SIMATIC STEP 7 can either be installed directly on the SINUMERIK 840Di sl PCU or on an
external computer (PG/PC).
SINUMERIK 840Di sl
If SIMATIC STEP 7 is installed on the SINUMERIK 840Di sl, no additional Ethernet cable is
required to load the S7 configuration in the PLC.
Windows applications executed on the SINUMERIK 840Di sl have direct access to the PLC
through the "CP 840D sl" communication processor.
The installation of additional software on SINUMERIK 840Di sl is described in Chapter
"SW
Installation/Update and Data Backup" (Page
551).
External computer (PG/PC)
If SIMATIC STEP 7 is installed on an external computer (PG/PC), it must fulfill the following
conditions:
● PG/PC interface is parameterized (see Subsection
"External Communication Link:
Ethernet" (Page
156))
● An Ethernet-Connection exists between the external computer (PG/PC) and the
SINUMERIK 840Di sl.
