morasse Posted February 5, 2020 Report Share Posted February 5, 2020 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? Quote Link to comment Share on other sites More sharing options...
Cam Posted February 5, 2020 Report Share Posted February 5, 2020 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? Quote Link to comment Share on other sites More sharing options...
Kikis Posted February 6, 2020 Report Share Posted February 6, 2020 Hello, ATV320 comes with only a serial port as standard, if you want to use Modbus TCP you need to add VW3A3616 Ethernet module. BR, KIKIS Quote Link to comment Share on other sites More sharing options...
MVP 2021 Joe Tauser Posted February 7, 2020 MVP 2021 Report Share Posted February 7, 2020 You can also configure port 2 on the V570 to do RS485. Look at page 6 on the specification guide - https://myzone-kza3sadj.netdna-ssl.com/wp-content/uploads/2015/12/V570-57-T20B-J_INSTAL-GUIDE_02-15.pdf 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. Joe T. Quote Link to comment Share on other sites More sharing options...
