I'm getting ready to do a lab on communicating directly from an Automation Direct HMI to a Yaskawa V1000 using Modbus RTU. Surprisingly, I've never worked with Modbus, and I probably should know how. We do work with a lot of Yaskawa drives, and they all come with embedded Modbus RTU. I chose the EA9 because it's inexpensive, and I have one available in my shop to play with. I'm not really finding much about configuring a Modbus connection in the EA9, which makes me wonder if this has a chance of working. My laptop with the software is at my shop, so I haven't looked at the communication config yet. For those who know more about this, do you think it'll work? An HMI is really a master, and the VFD is a slave device... so in theory, it should. Right?
