Hello indra;

Try the following manual:

Hope this helps,

Hi, Mr Chartier,

Thank you very much for your fast response.
Unfortunately, I can not find what I am looking for in this PDF file because in this PDF only show about IM 308-C, in fact the board that I am looking for is IM 308-B ( 6ES5 308_3UB11 )

It may be a different model but the fault LED's will have the same meaning.

BF LED is described on page 48. On solid could be a short, baud rate incorrect, basically described as a physical fault. If its flashing then there's is a slave fault.

for S5 115u manuals.

The BASP light is telling you that the outputs are disabled.
