BhimLama Posts: 13 Rating: (0)	Dear Expert! I have problem with analog signal processing. In my application, I use AI module (AI8x12 bits,331-7KF02-0AB0) for measuring the voltage signal 0-10V of a potentiometer. I gives the address for analog input as below. 1. data type: INT, address=%IW306 2. date type: INT, address=%IW308 and so on. It always shows the error in the programming. But the digital input and output work perfectly. Please, can you help me with this problem? Thanks you !! :)

Also check on the side of the module that the connector which have (A,B,C & D) is in its right position and matches the HW configuration setting.

I have one suspiction about one error, but first I would like to hear what CPU are you using. Please provide MLFB.

Thanks you !! :) During Hardware Configuration, in the Module Configuration You need to defined the Signal Type Like 0-10V, 2 Wire, 4 Wire, RTD or TC with respect to above you will get the A B C or D No. & it need to place on the Module, As mention in Above post,

In S7300/400/400-H PLC, while using FC105 scaling block you must write address with PIW and data type must be integar. In PCS7 while using Ch-AI block you must write address with IW and data type must be word. In S7200 while using scaling library block you must write with AIW.

In TIA there no more PIW if we speak about TIA. Here you write %IW306:P
