I have aFHsystem with 412-3H (6ES7 412-3HJ14-0AB0) PLC. I am facing trouble downloading the program in the CPU. I have 2MB ram (6ES7 952-1KL00-0AA0) ineach CPU. The error message is "For module with memory cards, the safety related program cant be reloaded" I have tried the option download in memory card. But it doesnt work. I am attaching the screenshots of the message. Please help!!! Thanks Pankaj Agarwal AttachmentScreenshots.zip (257 Downloads) |

Hi, As per your screen shot problem is your work memory.see the memory status of work memory in diagnostic buffer.if above 98% or more you cant able to download your program.other wise you have to change the CPU.. The folloeing FAQ will explain the procedure you need to follow: S7-400: Saving the user program to FLASH EPROM when the module is slotted in the CPU Note that you will have to write the complete program to the EPROM every time you need to save a change. And there is a write limit to a Flash EPROM. For development purposes, we would rather use a RAM card (you simply save your changes, incriminentaly,as you go along), and maintain battery support during that phase. When the project is finalized, we would transfer it to the flash EPROM so it would be preserved without battery. |
