Hello Enders first thing that comes to mind is that you may have an I/O address list DB1 in use in your program. If so, you MUST add the new I/O card addresses toit and below is link which more on this as well asthe relevant manuals in case you don't have them already: "Track 9", DB1 S5-155U CPU 948 Programming Guide SIMATIC S5-135U/155U System Manual The alternative solution is that you did NOT do a COLD restart after you added the new I/O card to your system. I hope this helps and should the above not be the cause of your problem, please give us more details and system architerue description (e.g.is the card located in the central or expansion rack, what other cards exist in your system etc.). |

Dear fritz, It does not have a DB1 but it has a DB0 as attached. The centralized CPU is installed in the controllers unit and all I/O modules are installed 4 other expansion units. Those units are linked with IM308/IM318. The I/O/F list is attached for reference. Yes, I have not performed a restart yet after installing the modules. It is because it is non-stop machine; I will arrange to restart it at this weekend. Hope the problem can be fixed. Thank you very much. AttachmentS5 new modules address problem.zip (355 Downloads) |

Hello Enders a COLD restart is mandatory for your CPU to reckognise the new I/O card so this explains why your CPU can't "see" the new card (and allow me tosuggest youpower off the rack before you insert a new card into it). As you mentioned that your new I/O is located in Expansion racks viaIM318/308 usage, make sure to grab the two manuals below and follow the proper restart procedure (the main rule in this case is that thepower supply of the expansion unit is switched on before or simultaneously with the power supply of the central controller). 318-3UA11 Central Controller Interface Module 308-3UA12 Expansion Unit Interface Module I hope this helps |
