C1@ndestin0 Posted March 23, 2018 Report Share Posted March 23, 2018 Hello all. I'm new programmer with Unitronics PLC. At moment trying to communicate USP-104-B10 with VFD ATV630 series by Schneider Electric, but unfortunately for me unsuccessfully. In PLC communication created Scanner and Adapter, add strucs with global tags according manual https://download.schneider-electric.com/files?p_enDocType=User+guide&p_File_Id=9346677116&p_File_Name=ATV600_EthernetIP_Modbus_TCP_Manual_EN_EAV64328_03.pdf&p_Reference=EAV64328 But I do not understand clearly what I need add in Ladder to read all needed parameters, for example, every 5 secs and how to CALL it? Maybe one of you have example of program with successful communication? I would be very appreciated. Thank you in advance for your help and reply Quote Link to comment Share on other sites More sharing options...
MVP 2023 Joe Tauser Posted March 25, 2018 MVP 2023 Report Share Posted March 25, 2018 This is a Modbus TCP device. You don't need to write ladder logic to call the drive. Look at the Help on setting up a Modbus TCP table- it will automatically poll the drive based on your requirements. Joe T. Quote Link to comment Share on other sites More sharing options...
