I'm thinking of upgrading a very old Sy/Max 100 to a Click, and am trying to do it as cheap as possible. Looking through Click options, I see there is a Basic CPU, and a Standard, the Basic not having a battery backup.
C0-00AR-D no Battery Backup
C0-01AR-D w/ Battery Backup
While not a huge difference in price, it'll be almost 43 dollars with the upgrade and the battery. I'm trying to figure out if I really need the battery backup.
I understand the actual PLC program is stored in non-volatile memory, so I won't lose that. But what about timer instructions? Will they lose their set values if it's powered down longer than the super capacitor can support? I plan on having a dozen or so timers, and four of them will have adjustable times set from a C-more Micro. Any advice? Thanks.
