Profinet Communication; Supported Telegrams - Siemens SIMOTICS S-1FL6 Operating Instructions Manual

PROFINET communication

PROFINET IO is a real time protocol based on Ethernet. It is used as high level network for
industrial automation applications. PROFINET IO focuses on the data exchange for a
programmable controller. A PROFINET IO network consists of the following devices:
● IO controller: typically, it is the PLC, which controls the whole application
● IO device: a decentralized IO device (for example, encoder, sensor), which is controlled
by the IO controller
● IO supervisor: HMI (human machine interface) or PC for diagnostic purposes or
commissioning
PROFINET supplies two kinds of real time communication, that is, PROFINET IO RT (Real
Time) and PROFINET IO IRT (Isochronous Real Time). The real time channel is used for IO
data and alarm mechanism.
In PROFINET IO RT, the RT data is transferred via a prioritized Ethernet frame. No special
hardware is required. Due to this prioritization a cycle time of 4 ms can be achieved.
PROFINET IO IRT is used for more precise timing requirements. Cycle time of 2 ms is
possible, but also special hardware for IO devices and switches are required.
All diagnostic and configuration data is transferred via the non-real time channel (NRT). For
this purpose the common TCP/IP protocol is used. Anyhow, no timing can be guaranteed
and typically the cycle times can be more than 100 ms.

Supported telegrams

SINAMICS V90 PN supports standard telegrams and Siemens telegrams for speed control
mode and basic positioner mode. You can select the desired telegram with parameter p0922.
See the following table for details.
From the perspective of the drive unit, the received process data represents the receive
words and the process data to be sent represents the send words.
