The ControlLogix uses TAGs instead of I/O addressing to do ladder logic. My HMI software does not support TAG addressing. Can I change the A-B to use I/O addressing?
It's been a while since I did it but it was pretty straight forward. Look at the attached file to see where to click. Enter the Array variable and a PLC5 style address - such as F8 or N7. Someone else said there is a driver that will read the ControlLogix - that would be the way to go ideally.
There are two ways to go:
- DF1 and mapp CLX-tags
- Use the CLX driver over ethernet
You will get better performance if you use the ethernet driver prior the serial DF1.
