4.3 PROFINET interface (C240 PN)

4.3 PROFINET interface (C240 PN)
Definition
A SIMOTION C240 PN provides an interface for connecting to PROFINET IO with three ports
(X11 P1, X11 P2, X11 P3) with a transmission rate of 100 Mbit/s. The PROFINET interface
supports the parallel operation of:
● IRT with the "high flexibility" and "high performance" options - isochronous real-time
communication:
– Equidistant transmission of input/output data between an IO controller and its IO devices
– With the aid of IRT "high performance", IO devices (I/O modules and drive units) that
● RT - real-time communication: Transmission of input/output data between an IO controller
and its IO devices in prioritized Ethernet message frames, but not isochronously. The
required bandwidth is in the bandwidth of PROFINET IO reserved for cyclic data.
● Standard Ethernet communication such as TCP/IP, UDP, HTTP, FTP, etc. as well as
communication with STEP 7 / SIMOTION SCOUT and communication with SIMATIC NET
OPC:
The required bandwidth is in the free bandwidth of PROFINET IO.
A SIMOTION C240 PN can be used as IO controller or I device. PROFINET IO differentiates
between an IO controller and the IO devices assigned to it. IO controller and IO devices form
a PROFINET IO system, comparable to a master-slave system on PROFIBUS DP.
Connectable devices
The following devices can be connected to the PROFINET interface:
● PG/PC programming device
● SIMATIC HMI devices
● SIMATIC S7 controllers with PROFINET interface
● Distributed I/O (e.g. SIMATIC ET 200M) with PROFINET interface
● Drive units with PROFINET interface
● SIMOTION devices with PROFINET interface according to PROFIdrive profiles /
IEC61800-7
44
with high stability for time-critical applications (e.g. motion control). The required
bandwidth is in the bandwidth reserved for cyclic data. For "high flexibility", a fixed
bandwidth of the transmission resources is reserved for the real-time communication.
The "high flexibility" enables simple planning and expansion of the system. For "high
performance", a fixed bandwidth of the transmission resources is also reserved for the
real-time communication. The data traffic is further optimized and accelerated through
an additional topology planning. The "high performance" option always requires a
configuration of the topology.
support IRT can be operated isochronously on PROFINET IO and data can be
exchanged between the SIMOTION devices via the controller-controller data exchange
broadcast.
