krolfson Posted August 25, 2022 Report Share Posted August 25, 2022 Is there an example of controlling an Oriental Motor AZD-CD drive (w/stepper) by modbus to Unitronics US7-B10-TA30 PLC? Do I use the ethernet port to connect to the drive? The motor driver has RS485 inputs. I can control this motor via direct I/O but can't get its position...so I figured that I need to go with modBus. Is there another way? Thanks! Quote Link to comment Share on other sites More sharing options...

No, ethernet port can't be used. You must add com module to PLC with RS485 function - UAC-CX-01RS4 Quote Link to comment Share on other sites More sharing options...
