(2) Introduction to Siemens Industrial Ethernet Communication Method

Industrial Ethernet communication mainly uses Layer 2 (ISO) and Layer 4 (TCP) protocols.

The Ethernet interface of the SIMATIC S7-1500 PLC system supports two types of non-real-time communication: Open User Comunication (OUC) communication and S7 communication, while the real-time communication is only PROFINET IO communication.

Siemens touch screen and PLC Ethernet communication steps

In actual production, we often encounter situations where one PLC cannot meet process requirements, such as insufficient number of high-speed pulse channels or insufficient number of analog input/output channels. If a large PLC is replaced, the cost will increase significantly. At this time, we can consider using mu
