Hello, Can you upload the buffer of CPU in case of error? Did you had problem in case of calling FB58 in OB35?Can you upload some part of your program related to PID controllers?Please also check memory requirement of the mentioned block and related Instant Data Block on your CPU(As shown in attachment). Also check: FB58 Issues Best regards Hamid Hosseini |

Also check: FB58 Issues Best regards Hamid Hosseini hey, thanks for interest; * I opened the CPU buffer and the massage was "illegal command" , I select "open block" , a massage appeared to me asked me if I want to open the block offline !! _the problem was in OB1 and OB1 didn't download on CPU_ so IConfirm it, the network that contain the PID parameters had the problem , and I diidn't know what it is ! I will attach a photo of massages when I can , I'm so sorry :( * Actually I don't know if I have a problem in calling FB58 , but when I downlod and compile the program on simulater it works very good , but when I trying to downlod it to CPU I have the problems that I mentioned before ! * here some parts of the program where is the problem should be ! the station has a 16K internal mempry and 64K MMC !
sorry , it's seem i talked too much |

Hello, I have some points to share on your case: 1- Simulating module is only simulating code executions and limited interrupts. Its behavior in some cases is far from reality. 2-I still suspect the memory constrains in your CPU.You can provide memory requirement of your whole project for work and load memory.To do so, select the "Blocks" folder, right click and see the properties.In "Blocks" Tab check "user program memory".You can upload the snapshot here for further investigations. 3-Next time to download the program and facing same error, save diagnostic buffer of CPU as text and upload it here. STEP7 inform you with an alarm message that the task is illegal.You can check the "Help" associated to this alarm. 4- Also check,The Maximum allowable flag number you can use is "256" bytes and you are using "MD306" and I also agree with CPU that is illegal. The final note, you can make a folder and copy all attachment you want to upload here and create a ".ZIP" file out of them.Also be careful of size limit of uploading files in the forum (3MB). Best regards Hamid Hosseini |

Hello friends , Thank you for all your feed-backs and this will help us to refer people with same problem to this thread in future. That is great to have a real view of what happening in your case.
Sorry for writing somehow unclear in this case.As my friend MarcJan mentioned, there are limits for resources in all CPUs and it is really annoying for people who worked with Giant S7-400 CPUs.For each CPU and order number you can search in SIEMENS online support and check the limitation as I did for your case: 6ES7312-1AE14-0AB0 Check again the maximun number of fags ,SIMATIC Timers,Simatic counters and... .These are all limited and you can not freely select any byte number you want. Best regards and Good Luck for your case Study Hamid Hosseini |
