Do the AC500 eCo PLC need memory module or backup battery to keep program at power down?
I do use an AC500 eCO PLC , each time i desconnect the power from the CPU i find out the the application program had been lost .
do i have to use memory card for saving the program?
what is the type of it? is it something that i need to buy from ABB?
do i need to install additional hardware?

You need to done "Create Boot Project" in online during PLC in Stop mode to ratian PLC Program. But it cannot reatain the set values in HMI / SCADA to do the same you need to buy Battery for AC500 eCo PLC (Modelno: CR 2032) or You need to move the Set values to retain Memory and again the same to move to PLC memory..
