PROFIBUS DP and PROFINET IO Differences

The instructions in this document apply to both PROFIBUS DP and PROFINET IO. Siemens® TIA Portal and SoMove™ software use the same mechanisms for PROFIBUS DP and PROFINET IO bus coupler systems. However, there are minor differences in how devices are addressed between the two bus systems.

In general, most of the differences are addressed by SoMove™ software. SoMove™ software will create the appropriate structures in the exported AML file for each of the bus systems. You might still need to manually set some parameters for the function blocks in the Siemens TIA Portal.

PROFIBUS DP uses a Numeric node ID for addressing. PROFINET IO uses an IP address or a PROFINET name for addressing. If the addresses are assigned in SoMove software, the addresses are automatically transferred in the AML file. Otherwise, the Siemens TIA Portal automatically assigns default addresses.
