Hello, I have just a little problem with the interpolation between 2 points. In TIA 13 I usually use the function "calculate". This helps me to create for example a heating curve. However, I cannot use this function for the ET200S CPU, but I found the code for linear interpolation in converting toolbox. Could anybody translate it for using in ET200 CPU, please? If the similar code has already existed, please just let me send the Iink. I would appreciate it very much.. Thank you.. Attachmentlinear.zip (518 Downloads) |

This is an example written in SCL in this thread:- https://www.automation.siemens.com/tf/WW/en/Posts/76267 Not sure if the S7-200 supports SCL though. If not, I could produce an STL equivalent if you twisted my arm . I will not produce it in LAD or FBD though as I cannot stand using those awful languages . |
Programming today is the race between software engineers building bigger and better idiot proof programs, and the universe producing bigger and better idiots. |

Hi smiffy, thank you for your effort you gave to creating this code. But I've got some troubles in declaration of variables. Fortunatelly I have found out that ET200 CPU supports the SCL code too. So for those who want to use this function, I attached this function. I am very sorry for your valuable time.. AttachmentLinear.zip (553 Downloads) |
