Hi, I'm working on my final year project. I am interested in programming the plc through PC, which inturn will command VFD drive through serial communication port as uploaded in the picuture below. Problem is, my plc s7 200 CPU 224 provides with only one rs 485 port. How do I use builtin rs 485 plc port to communicate with PC and VFD aswell? Can I make some arrangment likethisand solder three db9 ports? I am very new in automation and any kind of help will be appreciated. |
