Hi All, The goal: I would like to send messages to my Schneider ATV12 VFD using Modbus RTU. I understand I can send Modbus messages using freeport mode on port 0 or port 1 of the CPU 224XP. The problem: CPU 224XP has a DB9 female port, ATV12 has an RJ45 port (although RS-485 is the physical medium). I can't find any working examples of such a connection so I'm not sure if I have the right idea. Here's what I think could work: Take this cable (VW3A8306D30), find its pin assignment and attach this DB9 male connector (D-SUB Bus Connector 2310808) to the end. Where I Need Help:
Is anyone familiar with this problem AND/OR able to help? |
