Hi,
I have the same issue. After an upgrade from 1.13.9 to 1.18.60 the IO modules were blinking green or red.
The modules in question are: 0808T, 0808THS, UAG-XKXXXX, 0402N, 0402N, 0808T, 0808T.
During the upgrade, I have upgraded the PLC, IO units and the CPU FPGA. But not the CPU boot.
To solve the issue: The PLC is downgraded to its original state 1.13.9, including CPU FPGA and IO units.
How can this be resolved? There are still 2 machines with older firmware, but at this moment I am not going to gamble a 3 hour down time when the upgrade is not functional. 1 machine is already upgraded to 1.18.60 which went fine, this machine contains the following IO units: UAG-XKPL,0800N,W1+616T,W1616T, 0808THS.
Thanks, Maarten
