Hello,

Does BM! and CMR2040 have enough power to send SMS immediately when there is loss of power supply? Or is there any way to send SMS without need to use UPS?

Hi,

A CIM can send a SMS on power fail. Look for : 6ED1055-5MC08-0BA2.

Exactly, with CIM module you are able to set up the message for event of power loss and when power back to your system.

The set up system is done thru its webserver, very simple.

Hope it helps.
