Re: Shared variable engine modbus - Getting a stepper motor to work

$

Hello Fromm8

 

Yes, I tried following the guide and when I get to step 14 and try to run the program I get a couple different errors. I have attached a document that shows the errors.

 

 

The first error makes me think there is a problem with the RS485 converter I have that links the stepper motor to the computer. But I have followed the instructions properly nad called their IT guy to verify.

 

As for the communication settings, I have been over them many times and feel pretty confident they are correct. Acreenshot is attached in the document.

 

We are definitely using "Modbus Serial", the address on the driver is set to "2", the serial port is definitely "COM6" which is the RS485 converter to the driver. Baud rate setting on the driver is also set to 9600, and the transmission mode is set to RTU.

 

I am not sure what the Distributed System Manager is...

 

I really appreciate the help!
