John_R Posted September 11, 2020 Report Share Posted September 11, 2020 Hey All, I'm in the midst of upgrading an older V120 project to a V350. The V120 has two installed serial ports; I use Port 1 for programming and Port 2 for RS485/MODBUS to an AB VFD The V350 has one installed serial port along with a USB port. The spec sheet says; "Note that physically connecting a PC to the controller via USB suspends RS232/RS485 communications via Port 1. When the PC is disconnected, RS232/RS485 resumes." So, in essence this means I could use Port 1 for my RS485/MODBUS, and can plug into the USB if I need to program. I guess the downside is that I would not be able to see the MODBUS data in debug. So my inclination is to add in the second serial port. But... at some point in the future I may want to add an ethernet card... Question is, can I install both a second serial card and an ethernet card? JohnR Quote Link to comment Share on other sites More sharing options...
MVP 2022 Flex727 Posted September 11, 2020 MVP 2022 Report Share Posted September 11, 2020 I pulled a V350 off my shelf here in my office, and looking at it, I don't see how you're going to install both a 2nd serial port and an Ethernet port simultaneously. I could be wrong though. Quote Link to comment Share on other sites More sharing options...
John_R Posted September 11, 2020 Author Report Share Posted September 11, 2020 I just put an ethernet card in a different V350 a couple days ago, had to dis-assemble down to the bottom (front) as it mounted underneath everything and ended up in the lower port hole, you break the little hole cover in half and put it in to fill the top hole. I thought maybe the serial card somehow mounted above that, but I don't know as I've never added a serial to a V350.... Quote Link to comment Share on other sites More sharing options...
MVP 2022 Joe Tauser Posted September 11, 2020 MVP 2022 Report Share Posted September 11, 2020 On a V350 it's either Ethernet OR COM 2. Not both. Joe T. Quote Link to comment Share on other sites More sharing options...

Best option - install Ethernet card now and use it for Visilogic connection and programming. You can use it in future for another purpose (URB I/O, remote control ...).

This right here is the smart answer. Quote Link to comment Share on other sites More sharing options...
