If you are using Flash RAM backup,

save the changes you make in your

program and/or system configuration at

the end of each edit session. The

Save to Flash command is issued from

your panel software.

Whenever PLC power is lost and then

restored, the system firmware first at-

tempts to restore any battery-backed

memory. If there is no battery-backed

memory, then it will restore any configu-

ration and/or programming information

stored in Flash—remember that infor-

mation in Flash is only as current as the

last time you issued a Save to Flash

command. If there is no user memory

saved in Flash, the firmware will assign

the PLC a set of default configuration

parameters and no logic program will

exist.
