I had a program in S7 1214C which i am migrating it to S7 412-2 PN (TIA portal v17.0.0.0) and i found out get_im_data block doesn't work for 412 CPU. So i am looking out for an alternative right now. My complete program is in SCL and i am not well verse with using SFC. Can you help? ------------------------------------------------------------------------------------------ Split from How to read serial number of MODULE ?.

In case the SFC is not available in the S7-400 you need to implement this function by programming it yourselves. Scott

So you end up thinking that the number is the representation. - Andrej Bauer Any claims against me - based on whatever legal reason - resulting from the use of any code and/or ideas presented on this forum shall be excluded. #StayWithUkraine
