Two Comfort HMI one PLC

3 posts in this topic

I have two HMIs connected to one PLC.

The HMIs are identical. 

I'm downloading the same program to both and the only problem I have is that once it's downloaded to one I have to disconnect the network cable to download to the other. Is there a way to force TIA Portal to search for a target?

What is the best way to utilise two identical HMIs on one PLC, with the least work/pain?

The hmis should have different ip adresses and device names. And they also should have differently named connections to the plc.

Ok, thanks. I've got the different IP addresses. 

The connections are identical but it works. I think that has to be changed on all the tags?  What difference does the connection actual make out of interest. If I could read the packets going back and forth over ethernet would they be different?
