Manual, 09/2016, A5E35306440-AB
The CPU 1512C-1 PN has a PROFINET interface (X1) with two ports (P1 R and
P2 R). It supports not only PROFINET basic functionality but also PROFINET IO RT
(realtime) and IRT (isochronous realtime), which means you can configure
PROFINET IO communication or realtime settings on the interface. Port 1 and port 2
can also be used as ring ports for configuring redundant ring structures in Ethernet
(media redundancy).
PROFINET basic functionality supports HMI communication, communication with the
configuration system, communication with a higher-level network (backbone, router,
Internet) and communication with another machine or automation cell.
You can find more information on "PROFINET IO" in the online help of STEP 7
(TIA Portal) and the PROFINET Function Manual
(http://support.automation.siemens.com/WW/view/en/68039307).
With OPC UA, data is exchanged via an open and vendor-neutral communication
protocol. The CPU, as OPC UA server, can communicate with OPC UA clients such
as HMI panels, SCADA systems, etc.
