I need to communicate with a Fanuc R-30iB with a Red Lion HMI (CR3000)

I found a post where someone is using Red Lion HMI's to communicate with Fanuc Robots. I'm not sure what driver you use in your Red Lion HMI. You can search for SNPX and also $SNPX_ASG in the forum for more information. You can write directly to robot registers once you set up the $SNPX_ASG setting for it. You should also change the $NUM_CIMP parameter in $SNPX_PARAM from 0 to a 1.

You need the HMI SNPX option on the robot. In Crimson, you would use the GE/TCP/IP Master via SRTP driver. I use this method frequently as a low cost easy method to communicate with the robot. The HMI SNPX option is very low cost.

Each of these stories may not be the same.
