my current project contain CPU315-2DP, and 8x S7 300's unit ... what i need, is to make CPU recording temperatures, while power is cut down... that mean to backup power for AI unit (8 TC) and CPU 315 itself ... (additionally where may be an CP343) ... but i'm not familiar with siemens power sources yet ...
1) i've selected following configuration
+ 6EP1333-1SL11 SITOP POWER 5 STABILIZED 5A
+ 6EP1931-2DC21 SITOP DC UPS MODULE 24 V/6 A, W/O
+ 6EP1935-6ME21 SITOP BATTERY MODULE 24 V/7 AH
(w/o interface ... because i will be happy with this
those three binary signals saying me 'battery run'
and 'charge critical' '> 85% charged' )
2) would this be ok together?
3) does anybody used SITOP DC UPS practically with S7 here ?
4) wouldn't be better to buy on-line UPS (like from APC) and simply connect power source to it?
thanks for any help
