cataliz3er Posted January 9, 2015 Report Share Posted January 9, 2015 I have installed a UID-0808R IO module, and the PLC asks me to upgrade the firmware for it. Unfortunately this failed, so I have upgraded the firmware of the panel to 1.9.6. The same message appears: I/O units firmware upgrade failed OS upgrade for I/O unit #0 failed In the "IO Units Upgrade" section: ID: 0 OS File for Upgrade: UID-0808R_V_2_2 Current OS Version: 0.3 Any way to fix this?

Eyal Koren Posted January 11, 2015 Report Share Posted January 11, 2015 Hi, Please try the following: Go to UniApps-->Upgrade-->I/O upgrade. Mark the Forced check box and press Upgrade All I/O Units. Please let me know if that solved the problem. Quote Link to comment Share on other sites More sharing options...
