说明：  The configuration of an S7 connection between an S7-200 and an S7-300 via Ethernet has to be done on the one hand in STEP 7 Micro/WIN with the Ethernet Wizard for the S7- 200 and on the other in NetPro for the S7-300. For the Ethernet communication between the two stations you need communication processors and CPUs that support S7 communication. In this entry we have explained all the settings required for the S7-200 and the S7-300 using a sample configuration with CPU 226,
