CPU communication ports
There are four communication interfaces on the S7-200 SMART CPU that provide the
following communication types:
● Ethernet port:
– STEP 7-Micro/WIN SMART programming
– GET/PUT communication
– HMI: Ethernet type
● PROFIBUS port: The S7-200 SMART CPUs can support two EM DP01 modules for
PROFIBUS DP and HMI communication.
● RS485 port (Port 0):
– TDs/HMI: RS485 type
– Freeport (XMT/RCV) including Siemens-provided USS and Modbus libraries
● RS485/RS232 signal board (SB) (if present, Port 1):
– TDs/HMIs: RS485 or RS232 type
– Freeport (XMT/RCV) including Siemens-provided USS (RS485 only) and Modbus
(RS485 or RS432) libraries
