• Integrated Web server:
A Web server is integrated in the CPU. You can read out the following information with the
Web server:
– Start page with general CPU information
– Identification information
– Contents of the diagnostics buffer
– Querying module information
– Firmware update
– Alarms (without acknowledgment option)
– Information about communication
– PROFINET topology
– Tag status, writing tags
– Watch tables
– Memory usage
– User pages
– Data logs (if used)
– Online backup and restoration of the configuration.
– Diagnostic information for the motion control technology objects
– Display of trace recording stored on the SIMATIC memory card
– Readout service data

system, communication with a higher-level network (backbone, router, Internet) and
communication with another machine or automation cell.
The third PROFINET interface (X3 P1) has one port and supports PROFINET basic
functionality, i.e. no IO controller / IO device role. The basic functionality of PROFINET
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. As of firmware version V1.7,
the third PROFINET interface supports a transmission rate of 1000 Mbps.
NOTE
IP subnets
The IP subnets of the three interfaces must be different. This means that the subnets of
the IP addresses of the three interfaces must differ from each other.
The fourth interface (X4) is used to connect to a PROFIBUS network. When you use
the interface as PROFIBUS DP interface, the CPU is the DP master in this case. The CPU
cannot assume the role of a DP slave.
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.
