In the first message i was in autoconfig. What happened when I moved ECOM from slot2 to the empty slot1 and powered back-up the whole configuration vanished. Only the do-more module was visible. I power down and put ECOM back in slot2. Powered up and everything was OK again. Thinking that's strange, I power down, put ECOM back into slot1, power up and again all modules vanished except the do-more again. So I switch to manual config mode and manually scanned the base and still nothing. This time I stayed in manual mode for the above listed events. After the last message I turned off the plc. Today I cleared the memory completely, reloaded the firmware update, which I updated before with the plc project in memory at the time, reloaded the project and everything mentioned above went away. So I thinking when I did the system firmware update with the project loaded in memory, part of the system memory became corrupted. That's all I can come up with. Now it's working fine again.
I see that I'm have to purchase the ethernet version of the do-more in order to add in the next system upgrades.
