Each S7-200 SMART CPU provides an Ethernet port and an RS485 port (port 0), and the standard CPU additionally supports the SB CM01 signal board (port 1), which can be configured as an RS232 communication port or an RS485 communication port via the STEP 7-Micro/WIN SMART software.
The S7-200 SMART CPU enables a wide range of communication between the CPU, programming devices, and HMI (Human Machine Interface):
Ethernet:
Data exchange between the CPU and the STEP 7-Micro/WIN SMART software.
Data exchange between the CPU and the HMI.
GET/PUT communication between the CPU and other S7-200 SMART CPUs.
Open IE (TCP, ISO on TCP, UDP) communication between the CPU and third-party devices.
PROFINET communication between the CPU and the IO device or controller (S7-200 SMART V2.4 only supports PROFINET IO controllers, S7-200 SMART V2.5 and S7-200 SMART V2.5 support PROFINET controllers and IO devices).
RS485/RS232:
Data exchange between the CPU and the HMI (PPI protocol).
The CPU uses free port mode for serial communication with other devices (e.g., XMT/RCV communication, Modbus RTU communication, USS communication, etc.).
