Siemens S7-300 Devices capable of Profibus DP communication, Connecting to Industrial Ethernet

Communication

3.1 Interfaces

Note

(for DP interface in slave mode only)

When you disable the Commissioning / Debug mode / Routing check box in the DP interface properties dialog in STEP 7, all user-specific transmission rate settings will be ignored, and the transmission rate of the master is automatically set instead. This disables the routing function at this interface.

Devices capable of PROFIBUS DP communication

Availability

CPUs with a “PtP“ name suffix are equipped with a PtP X2 interface. X2.

Connecting to Industrial Ethernet

You can use the integrated PROFINET interface of the CPU to establish a connection to Industrial Ethernet.

The integrated PROFINET interface of the CPU can be configured via MPI or PROFINET.

Requirements

•CPUs with FW 2.3.0 or higher (for example CPU 315-2 PN/DP)

•STEP 7 V5.3 + Servicepack 1 or higher
