Hi Please check the attachment for memory requirement of Modular PID control and standard PID control blocks. regards AttachmentPID.zip (197 Downloads) |

Hello Tomy Master further to theabovesupplied links and references(which give you all the required infoto determine thetechnical data of the PID blocks), I'd like to add that the size of the MMC (which is the LOAD memory) is less of importance than the size of the CPU's WORK memory. Put simple, if your workmemory (CPU inbuilt and not expandable) isn't big enough, the largest Load memory (MMC) will not help you and below are afew links with more on this subject: How can you determine the size of the load memory and main memory of a SIMATIC S7-300/400 CPU? How many blocks can I load on an MMC and how much does this depend on the CPU used? I hope this helps |

Hello Tomy, http://support.automation.siemens.com/WW/view/en/18459342 These are the block which you could use for any PID controls..But you already knew this. Best regards, Hristo Mihalev |
