Kindly, we have the following Siemens module with a stop red led on . What could be the problem ? How can we diagnose this module ? It is installed on a S5 135u/155u rack next to a cpu928b . Thank you

6GK1143-0TA02 , SIMATIC NET CP 1430 TF Communications processor for Connection ... to Industrial Ethernet Basic-Version
 
we have the batteries of the S5 rack going off for some time, so we suspect that the CP has lost its program (or parameters?).
can we download to it again? or reconfigure it? using some engineering software?
thank you
