5.2 Standard telegram configuration

5.2 Standard telegram configuration
The standard telegram configuration of a SINUMERIK NCU can have different versions. This
depends on the safety mode, I/O addressing scheme and the firmware version used:
● Depending on the safety mode used, different telegram types are used for safety-relevant
communication. Telegram types for standard communication do not differ.
● SINAMICS Integrated V4.7 and V4.9 with Safety Integrated plus (F-PLC) uses different
PROFIsafe telegram types by default. The I/O start addresses of the telegrams are
identical, however.
Thus, the options and I/O addresses of the process data for controlling the SLS (safely
limited speed) and SCA (safe cams) are different.
● The optimized I/O addressing scheme (Page 107) provides a larger coherent address
area for other purposes and therefore uses different telegram I/O addresses (except for
PROFIsafe telegrams).
A telegram configuration with an optimized I/O addressing scheme is considered the
standard telegram configuration in this sense, but nevertheless requires additional
adaptations of the machine data (via SINUMERIK Operate) (Page 134).
Note
Safety Integrated plus (F-PLC): Different I/O addresses for telegram 701 in NCU V4.7 (TIA
Portal) and NCU ≥ V4.7 SP2 (machine data)
If you configure an NCU V4.7 (TIA Portal) but the firmware V4.7 SP2 (or higher) is used in
the actual hardware, the preset I/O addresses from the Siemens telegram 701 in the TIA
Portal do not match those in the machine data (MD10393).
• To establish compatibility with NCU firmware ≥ V4.7 SP2, you can adapt the I/O
addresses in the configuration.
See: Calling the telegram configuration (Page 111), Viewing I/O addresses in the TIA
Portal (Page 105), PROFIsafe/PROFIdrive telegrams for Safety Integrated plus (F-PLC)
(Page 130)
• Alternatively, you can adapt the I/O addresses in the machine data. In this case, your
telegram configuration is considered as user-defined telegram configuration.
