Hello All,
I am facing problem while downloading the S7-300 ladder to CPU. I tried browsing the Forum if someone had this kind of error, but couldn't come across any.
The ladder has been compiled tested on simulator first & runs fine, but when I download it to CPU it does not allow me to download any FC's FB's OBs. I checked the MMC card & its present. I have tried Mreset , online deletion of all blocks in the CPU memory & even downloading a truncated ladder which contains just OB1 with 1 N/W. Still the problem persists.
My hardware configuration is CP315-2DP, CP341 in Processor rack, Rack1 -Rack 5 containing I/O cards . All racks connected on DP/Profibus using IM153-1.
Any suggestions welcome.
Thanks,
