Hello Wasp; In adition to Marcjan's helpful code, you will find any number of hints on using FC105 "SCALE" on the forum, including this FAQ describing the specific use of all parameters of the FC. http://support.automation.siemens.com/WW/view/en/24148558 Simply remember that the IN parameter should connect to the PIWxxx address of the analog signal ot be scaled, and that Hi_Limit and Lo_Limit are ofREAL data type, and correspond to the engineering values you want to scale tyhe analog signal to. Example: your flowmeter is connected to address PIW256, and you want to scale this 0-27648 value (standard analog input) to a 0-20000 gpm value. Then your IN parameter is PIW256, your Hi_Limit is 20000.0, your Lo_Limit is 0.0, while your Bipolar parameter should be set to 0. Hope this helps, Daniel Chartier |
