Operation error

3 posts in this topic


I am developing an application with fx5u with inverter d700, it fails to send a command to the inverter, only running the application and monitoring the clp does not appear to fail, only when it sends a command. Attached photo of plc configuration and error. Do you have any secrets to doing communication, can I do it with a normal network cable? I'm doing with just one inverter, as the terminator should be at 110 or 330 ohm.

You have an exception response. so you are getting an answer from the slave that the command is incorrect.

Probably you are asking for a device that doesn't exist.

But Read the exception code to be sure

And also: If you are using 2-wire, then 110ohm, 4-wire then 330ohm.
