    Hi PMCR, I am using a CJ2M-CPU32 fitted with CP1W-C1F12 RS485 interface card, not SCU. Thanks anyway.

    Sleepy Wombat, I have read up on modbus and the command structure that is sent to the drives however have never got it to work. I will download and try Multiway and see if i can understand it better. Thanks to both for the replies and advice.

    Hi All, This is my first post so am sorry if anything is done incorrectly... I am having trouble with Modbus RTU on RS485 I have not worked with modbus before or Omron, So i am finding it hard to try and figure both out. The Hardware being used is: CJ2M PLC 3x 3G3RX Drives Is there a simple way of creating and sending the commands? ie a function block I have been looking around for a fb however i have had no luck with the ones i have found and i think it may be due to the RX Drives. Any help that can be provided will be much appreciated!
