Dear Sir or Madam, I would like to retrieve the status from the DI 16x24VDC ST Digital Input Module (6ES7131-6BH00-0BA0). I work with a S7 400H and STEP 7. I would like to recover the information of wire breakage, power supply voltage absent or low. What to do. I read that SFC 59, SFB 51 via OB82 could do the trick. But I do not know how to arrange it all. Thanks in advance. With best regards ------------------------------------------------------------------------------------------ |

Hi, here are some examples with SFC 51: How do you find out the status of the stations of a DP master system or of a PROFINET IO system? also check the following manual / one page 214 you will get informations about SFC 51, on page 144 you get infos abou sfc59. In chapter 33 you will find information about SSL/SZL System Software for S7-300/400 System and Standard Functions Regards, Towome |
