Hello, The base interface number (SSNR) specifies the CP in the rack. This interface number has to be used in the block calls in the S5 program. Check there http://support.automation.siemens.com/WW/view/en/22792412 Best regards, Hristo Mihalev |

Hello lisalxy UMENCHOis generally right, in your particular case though there is a bit more to it.
If the number in the high Byte of SSNR is uneqal to zero (which it is in your case as it has a value of 255) it means that indirect (or pointer based) assignment of the SSNR is used. In this case you'll find the "real" SSNR at the DWaddress of the low Byte of the SSNR.in the DB that it opened before the call. In you case it would be a DW50as your SSNR variableis KY 255, 50. Below are a couple of manual links which have more details on it and I hope this helps grap the one for your type of S5 and search them for SSNR): StandardData Handling Blocks for S5-135U, S5-155U S5-115U Programmable Controller |

Thanks UMENCHO for pointing that out! fritz, in the sample UMENCHO pointed out, the Base SSNR of CP1430TF was set at 8 in COM1430. and in the S5, the SSNR was also set at SSNR: KY 0,8 (thus the CP interface no. is being use here in S5). In my case, it is SSNR: KY 255,50. When I configure for another COM1430 call for my client, I am spps to follow their S5 and therefore, should the new call in COM1430, for the base SSNR be: Base SSNR: 48 with SSNR offset: 2? In COM1430, the base SSNR need to be divisible by 4. |

Hello lisalxy I fear I failed to be clear enoughin my previous post. "SSNR: KY 255,50" means indirect SSNR configuration and you need to look into DBxyas of DW 50 where you'll find the actual values. Attached is a pic from the 115U manual which will hopefully make it clearer this time, the same applies for 135 or 155U'susage of the Send/Receive blocks (see manual links in previous post). I hope this helps |
