Hello , Can you try reading data records of the corresponding modules with SFC59(Section 7.8 of this manual)? System Software for S7-300/400 System and Standard Functions Volume 1 and Volume 2 You can find structure content of DR for each module in the corresponding manual(appendix B): http://support.automation.siemens.com/WW/view/en/8859629 Best regards Hamid Hosseini |

Dear Hosseini, This also applies to 6ES7322-8BH10-0AB0 ??? I need to check wire-breaks from its channels... Another thing: When I configured some of this same module, the Q address sequence was automatic fixed in this way: Slot Q Address 4 0... 1 5 4... 5 6 8... 9 I didn't understand why has a "jump addressing" between 1 and 4, 5 and 8... This not occured with anothers modules in this HW Config... Regards! |

Hello Maselo; When you insert a digital (inpout or output) module in HWConfig, the editor automatically uses "slot-specific" addressing based on the maximum size of available modules: 32 bits, or 4 bytes. Then it removes the unsued bytes (without "packing" the addresses, that is without removing the unsused addresses). For example, the module you show in slot 4 starts its addressesat address 0. HWConfig would automatically reserve 4 bytes: 0, 1,, 2 and 3; but since it appears to be a 16 output module, only bytes 0 and 1 are retained and shown for the slot's addressing. Slot 5 moduleaddressing would then automativcallystart at address 4, and bytes 4.5.6 and 7 would be retained... Slot 6 would start automatically at address 8, with bytes 8, 9, 10 and 11 reserved.... and so on. In most CPUs now you can simply go tho the HWConfig editor and change the addresses of your digital modules yourself, manually, to "pack" the addresses in a sequence, if you prefer. This is all well explained and illustrated in chapter 7 ("Addressing") of the following manual: SIMATIC S7-300 CPU 31xC and CPU 31x: Installation Hope this helps, Daniel Chartier |
