Reviving this topic, I was on a site recently that had an S7-200 Smart on a Lneya chiller, this S7-200 had an ethernet port. Tried to connect using TIA both version 13.2 and 15.1 and no luck making a connection with either.
Had to screw with connection settings a bit but was finally able to connect, see IO status and pull a program using Step 7 Micro/win SMART V2.5 and an ethernet cable and switch. At least on the PLC side. No idea what I’d need to use to talk to the HMI which was not a Siemens product.
Here’s where I got V2.5 [Download] STEP7 MicroWIN SMART V2.5 for PLC S7-200 Siemens (GoogleDrive) - plc247.com
