V700 on a battery voltage source

[FrutigerAG]

Hello
I am using a V700 on a battery voltage source with 24VDC for a mobile measuring device. 
With a V700, is there a way to internally query the current supply voltage to be able to detect a possible voltage drop from the battery?

Thanks.

Inside V700 PLC present onboard DC-DC 24VDC to 5VDC.

From V700 manual:

Input voltage 12 or 24VDC
Permissible range 10.2-28.8VDC 

There is no internal circuit for measuring the supply voltage.

If you have a Snap-In module with an analog input - you can measure the input voltage through a resistive voltage divider.
