Hello oldnovice; You have put up many different problems that seem to require an examination of your system: you speak of memory problems with a S7-318-2DP, and difficulty in integrating new screens with an HMI software (unnamed as yet), and communication problems between the two. We need more information on your hardware and software before we can get a lear picture of your situation. First point: the S7-318-2 is an older generation of the S7 CPUs, it was actually a S7-400 in disguise inside a S7-300 case. The design was meant to allow faster processing times and larger memory in a smaller footprint, before the newer generation of S7-300 took over. Here is a list of acceptable Memory Cards (FEPROM and AM) that are acceptable to the S7-318-2DP, see if the one that was sent to you is included in the list; in this case it will work with your CPU, since it is designed for s7-400 CPUs. S7-300 CPU 318 and Memory Cards to Be Phased Out The program loading on your Memory Card will be different if it is a RAM Card (simple download of complete program to the CPU) or a FEPROM (the CPU must be in STOP mode; use the Copy RAM to ROM menu item in Simatic Manager). Check the online help or the forum entries (use the search box at the top right of this page) for more details if needed. If this has managed to fix your memory bottleneck problem, give us more information on your HMI system, how you are connected to it, and a better description of your communication and screen development issues. Then we should be able to provide better help. Hope this helps, Daniel Chartier |

HI Thanks for answering. I was sent a 6ES7 952-1KK00-0AA0 Memory card. I have a spare PLC set up as test rig so that I can have everything sorted out before implementing the changes for real. Equipment I am working with. Siemens Field PG with Windows XP Simatic s7-300 CPU318-2 TP1500Basic PN (1.8.3.0.2008SP2) This is already installed in the existing set up (using an Ethernet connection) but not on test rig. TP177B 6"ColourPN/DP(1,1,4,0 2008 SP2). This is the screen I wish to add and having connectivity problems using Profibus connection. The address on the screen is set to 8 as is the PG setting. Using WinCC Flex 2008 SP3Advanced UPD 5. When downloading on the Netpro screen I have this messsage in Doc 1. When I try to carry out the instruction to resolve this problem The configuration tab is not available in the window. AttachmentDoc1.doc (160 Downloads) |

Hello oldnovice; The memory card part number that you have received is definitely not part of the list that you have in the preceding post. These MCs are discontinued, so the only way you could get one (through Siemens) would be requesting one from Spare Parts (look them up using the Services link at the top right of this page, just below the Site Explorer search box). Or try to locate one from the Web. Your CPU can be slotted with MCs up to 2 MB RAM or 4MB FEPROM . Now, the S7RTM message that you show has been discussed on the forum in earlier posts. Here is one in which our friend Wizard has provided a solution: https://support.industry.siemens.com/tf/WW/en/posts/s7rtm-problem/82486?page=0&pageSize=10 If you want to see more threads on the subject, try the search box already mentioned, use a search term like "S7RTM". Hope this helps, Daniel Chartier |
