Communication error 7 (Incorrect address)

3 posts in this topic

Good day, i have a delta DOP -BV107 HMI integrated with a Delta DVP-14 SS2. The communication method is a RS232. I have checked all parameters, addresses and stations from the comms side countless amount of times, however I am still getting a write error communication error 7 (Incorrect address) on the HMI side. 

Can you please help with how I can resolve this and the method to take to do so ? Also if you need additional information from me to solve the problem. 

Kind Regards

I am not a Delta Expert, but screenshots of the Configuration Pages as you've programmed them would most likely be useful to the Delta folks.
