I have been working on a project for several weeks with no problem. Last night, I unplugged everything (previously it has just been left on all the time.) Today when I plugged it in, i get a "P499: Recv. ErrCode 021c ". Everything worked fine before I powered down the unit. Looking in the references, I can see that the error means that the PLC is password protected. I did set a password, but I thought it was to protect against unauthorized access... Surely the CMore Micro should be able to still connect to it though, correct? How do I go about this? thanks, Jon

To allow display access make sure your CPU pass word is the capital letter 'A ' followed by exactly 7 numbers.
