Hi, 

I am on my first project using visilogic and unitronic plc. 

I am currently trying to use the V570 to control a Altivar 320 Schneider VFD. 

The Altivar 320 have a RJ45 serial port on it (not Ethernet). My V570 is equip with the RJ45 (port3). 

I would like to use Modbus to made the communication between both using rj45 cable. 

Is it possible?

No the RJ-45 port on the V570 is an Ethernet port.  Why not make a conversion cable to go between the RJ -11 serial port on the V570 and your drive?

Hello,

 

ATV320 comes with only a serial port as standard, if you want to use Modbus TCP you need to add VW3A3616 Ethernet module.

You can also configure port 2 on the V570 to do RS485.  Look at page 6 on the specification guide -

You'll need to make or buy a cable with an RJ12 six pin connector using pins 1 and 6 to connect to your drive.  Unitronics offers a small stub cable for RS485 - MJ10-22-CS65.
