Hi,

In our 20Hi Rolling Mill , we have problem with FM458-1 DP module. It goes into STOP.

In CFC, "module information" said:

Error panels: no error

Exceptions: last crash , ID:  #4 USER, Supplementary ID: 54 ( User STOP triggered on this CPU)

This crash appear after a time between 1 to 4 hour. It is repeatable , with time delay.

To restart the FM458 module , I switched to STOP and again to RUN, and FM458 runs OK.

Please, help me to find the problem and to fix it.

Thanks you,

Dorin

Hi, 

I don t have an user conection to FM458. Just PLC and a PC with VB6 as HMI.  No PG.  No Siemens Simatic software on PC. 

Do You have another suggestion?  Could Be something wrong with Fm458 modules?  Like hardware problem?

Dorin

Hi,

before FM458 goes into STOP, I observed, for very short time, the EXTF LED lighting.

After this, the  STOP Led flashing for three times. And finaly STOP led lighting.
