yarikgp Posted August 10, 2013 Report Share Posted August 10, 2013 Hi, I have purchased two Jazz R16 PLCs, and trying to reprogramm them to my needs, the only problem I have got is that after I switch power off, all the data saved in the PLC is gone or restored to defaults. Also while I am recompiling the programm and trying to download the program to PLC, I see the power up values - retain values grayed out. What should I do to enable it? I have opened the Jazz, and have seen the Letium battery on board, so I beleave it is good battery, also SB8 return a 0 value. How can it be that the values does not been saved?
