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
● RT - real-time communication: Transmission of input/output data between an IO controller
● Standard Ethernet communication such as TCP/IP, UDP, HTTP, FTP, etc. as well as
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.

communication:
– Equidistant transmission of input/output data between an IO controller and its IO
devices 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.
– With the aid of IRT "high performance", IO devices (I/O modules and drive units) that
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.
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.
communication with STEP 7 / SIMOTION SCOUT and communication with SIMATIC NET
OPC:
The required bandwidth is in the free bandwidth of PROFINET IO.
