Hi ahmad_elec, you might only be able to read the serialfrom the actual master CPU. Does anybodyknow aboutan update from Siemens to get both serials? I don't see much use of reading the serials anyway. But this is only my opinion so please no comments on that . Best Regards. |

Reading serial numbers has a benefit in security. You can read the serial number of the CPU and put it in your program so that if the customer tries to replicate your program on other CPU, then it will not run

It does prevent customer from replicating your programs ... but also prevents him from a genuine replacement of MMC / CPU ( as the case may be ) in case of Hardware failure. A Fair practice in such cases is to add at least one additional serial no of a Spare MMC or CPU available with the customer for Genuine maintainence. Cheers Navnag |

ThanksUMENCHO Please attention to this note:System Software for S7-300/400 System and Standard Functions Volume 1 and Volume 2 Please check this section:13.3 Reading a System Status List or Partial List with SFC 51,"RDSYSST" , 34 System Status Lists (SSL) This note tell us when we want to read the serial number of one CPU we must use the SSL_ID#16#011c, but when we want to read the serial number of one component of all redundant CPUs of a H system, we must use the SSL_ID#16#031c with its index. In addition, I test your idea, but the result was the same, it means in the RET_VAL out put I get the 8083 error code! May be I'm wrong. please tell me. I'm waiting for your other suggestion. with regards.

Hi dearSte39 Yes, with both SSL_IDs W#16#031C and W#16#011C, 8083 error code appears. I test other index numbers (1,2,3,4,5,7) for SSL_ID W#16#031C and they work good, but when I use the 8 index umber, this error code appears!

Hi dearhdhosseini My CPU's properties is : CPU 414-4 H with firm ware 4.3. I used SFC 51 with SSL_ID W#16#031C and index W#16#0008 for read the serial number of MC from my CPU. I test the other SSL_IDs(11C,21C) but the result is same and the 8083 error code appears. Snapshot from my project is impossible for me, because it's location is so far from me! Thanks.
