Hello,
I believe I am having a similar issue related to the OS and boot versions of my PLC components. I have a Unistream 15.6" HMI/PLC with the following IO configuration as shown in the image attached.
The devices indicate the following status
UAG-XK125 - Solid Green Link Light (indicating communication connection to Base)
UID-0808D - Rapid Green Blink (indicating OS Initialization)
UIA-0402N - Slow Orange Blink (Unsure what this is Indicates)
UIA-0402N - Slow Green Blink (Indicating OS Boot)
The HMI displays a Pop-up after boot reading: "Uni-IO Communication Error please check power and cable connections". I have verified all communication and power connections are correct. After multiple reboots and different OS and Boot installations loaded, the cards still give me the same status. Any help would be appreciated
Thanks, AFlanagan
