BASP fault in S5-155H CPU 948RL

Dear All,

I'm presently working in S5-155H series. The CPU is 948RL. There are 02 no of controllers.

In one controller the BASP indicator is blinking & the CPU is set to STOP mode.

Can anyone suggest that how can I switch the CPU to RUN mode & remove the BASP fault!

Regards

OmKris
